  • The author investigated the values of total serum cholesterol and its coreelation with the physical factors to have potential as a line in the chain of basic investigation to establish maternal health program. The study group was composed of 167 healthy non-pregnant and 209 pregnant women in the age of 20-39 residing in Pusan area. The obtained results were as follows : 1. No significant differences were found in height and systolic and diastolic blood pressure in both groups except for the elevation of Broca's index by gaining the weight in pregnant women. 2. There were significant differences in the total serum cholesterol level of the healthy and pregnant women as 165.9 mg/dl and 212.6 mg/dl, repectively, not showing the differences in the age. Total serum cholesterol values in both group followed approximately normal distribution curve. 3. The significant correlation to the values of total serum cholesterol were found between weight and Broca's index in healthy women and between weight, Broca's index and duration of pregnancy in pregnant women. 4. The values of total serum cholesterol by weight were 162.9-189.4 mg/dl in healthy women and 167.2-246.2 mg/dl in pregnant women, showing the increasing tendency of values by weight, especially in pregnant women. 5. The values of total serum cholesterol in pregnant women showed increasing tendency with the duration of pregnancy as 168.1 mg/dl in 12 weeks and below, 209.6 mg/dl in 13-26 weeks and 235.4 mg/dl in 27 weeks and above group. Total nm cholesterol values by duration of pregnancy followed normal distribution curve.

  • Neonatal bleeding is a common problem encountered in nursery rooms or neonatal intensive care units, especially among premature infants. Furthermore, owing to recent remarkable improvement of neonatology, survival rates of preterm neonates have increased; hence, neonatal bleeding cannot be emphasized enough. Since the total blood volume of neonates is small, bleeding can be one of the causes of morbidities and mortalities. Therefore, rapid diagnosis and immediate therapy is urgently needed. The patient's medical history including a familial history of a bleeding disorder or of a previously affected infant who suffered from bleeding along with maternal and neonatal drugs can provide important diagnostic clues. Presence of bleeding with or without petechiae and ecchymoses in a healthy term or late preterm infant with thrombocytopenia but normal prothrombin time and activated partial thromboplastin time strongly suggests a congenital bleeding disorder. For a sick infant who is bleeding from multiple sites, an acquired disorder such as disseminated intravascular coagulation is suspected. Intracranial hemorrhage in term or late preterm infants without a history of birth trauma is highly suggestive of coagulation disorders. The purpose of this review is to summarize recent advances in diagnostic methods is as well as basic concepts of neonatal hemostatic disorders. First, an outline of background information will be presented followed by a discussion of primary and secondary hemostatic disorders as well as inherited and acquired disorders.

  • A 3-year-old, female spotted hyena (Crocuta crocuta) was referred with dystocia. The hyena had been in labor for over 5 days, but she failed to expel the infant. The blood biochemistry profiles showed severe azotemia. During caesarian section, we confirmed that the uterus had expanded and contained 1 dead, decayed infant, which compress the urethra, leading to the expansion of the urinary bladder and that the dead fetus was nearly 3 kg in weight (approximately 5% of the maternal weight). Thus, we confirmed that the dystocia caused by oversized fetus and malposture, and the severe azotemia resulted in compression of the urethra by fetus in the hyena. This report is the first to show that the dystocia can induce postrenal azotemia in female spotted hyenas.

  • Transient neonatal diabetes mellitus (TNDM) has been associated with paternal uniparental isodisomy of chromosome 6, paternally inherited duplication of 6q24, or a methylation defect at a CpG island of the ZAC or HYMAI gene. We experienced a case of TNDM in which the patient presented with hyperglycemia, macroglossia, and intrauterine growth retardation, caused by a paternally derived HYMAI. An 18-day-old female infant was admitted to the hospital because of macroglossia and recurrent hyperglycemia. In addition to the macroglossia, she also presented with large fontanelles, micrognathia, and prominent eyes. Serum glucose levels were 200-00 mg/dL and they improved spontaneously 2 days after admission. To identify the presence of a maternal methylated allele, bisulfite-treated genomic DNA from peripheral blood was prepared and digested with BssHII after polymerase chain reaction (PCR) amplification with methylation-specific HYMAI primers. PCR and restriction fragment length polymorphism analysis showed that the patient had only the paternal origin of the HYMA1 gene. TNDM is associated with a methylation defect in chromosome 6, suggesting that an imprinted gene on chromosome 6 is responsible for this phenotype.

  • Objective: To conserve and utilize the genetic resources of a traditional Chinese indigenous pig breed, Liangshan pig, we assessed the genetic diversity, genetic structure, and genetic distance in this study. Methods: We used 50K single nucleotide polymorphism (SNP) chip for SNP detection of 139 individuals in the Liangshan Pig Conservation Farm. Results: The genetically closed conserved population consisted of five overlapping generations, and the total effective content of the population (Ne) was 15. The whole population was divided into five boar families and one non-boar family. Among them, the effective size of each generation subpopulation continuously decreased. However, the proportion of polymorphic markers (PN) first decreased and then increased. The average genetic distance of these 139 Liangshan pigs was 0.2823±0.0259, and the average genetic distance of the 14 boars was 0.2723±0.0384. Thus, it can be deduced that the genetic distance changed from generation to generation. In the conserved population, 983 runs of homozygosity (ROH) were detected, and the majority of ROH (80%) were within 100 Mb. The inbreeding coefficient calculated based on ROH showed an average value of 0.026 for the whole population. In addition, the inbreeding coefficient of each generation subpopulation initially increased and then decreased. In the pedigree of the whole conserved population, the error rate of paternal information was more than 11.35% while the maternal information was more than 2.13%. Conclusion: This molecular study of the population genetic structure of Liangshan pig showed loss of genetic diversity during the closed cross-generation reproduction process. It is necessary to improve the mating plan or introduce new outside blood to ensure long-term preservation of Liangshan pig.

  • This paper presents the results of a survey for the causes of sensori-neural hearing impairment in Korea, The subjects were 1,676 children of total 2,928 enrolled in 16 Deaf Schools; two schools in each area of Seoul, Busan, Kyoungbook, Kyoungnam, Kyounggi and Chunbug, and each one in Chungnam, Chungbug, Chunnam and Jaeju. The data were collected by questionaire with 28 items distributed to their parents. The filling in the check lists were performed by their class teachers, interviewer, for 18 months from September, 1975 to february, 1976. The questionable or missed problems were reaffirmed. The results obtained were as follows. Most of the reasons, 78.5% were acquired characters that could be developed during pregnant period, the time of delivery and the time of after birth. The pure hereditary reasons except the cases complexed with one or two were only 11.3%. Those who could not be defined with any reasons were 10.2%. Among the acquired causes, 5.8% of total subjects were developed for pregnancy: 3.3%, during delivery; and 69.7%, after birth. In the pregnant period, the drug intoxications were 2.4% of total subjects, several diseases such as influenja, bleeding, surgical operation, venereal diseases and rubella etc. were about one percent, and the accompanied with some symptoms of pregnancy intoxication and traumatic events were 2.4%, During time, the cases with delayed rhythmical pain were 16 persons, the immaturities were 11, the asphyxial cases were nine, the errors of forceps delivery were seven, the cases of low body weight inspite of full term were four, the cases with cesarian section were three, the head injuries were two, and the accompanied with three kinds of above reasons were three. During after birth, the cases with acute communicable diseases were 35.4% of total subjects, the fever unknown origin were 16.1%, the chronic otitis media were 3.7%, the meningitis were 3.5%, the gastric and nutritional diseases were 3.5%, the drug intoxications were 4.8%, the blood diseases were 0.3% and the other causes were 2.2%. Here by acute communicable diseases, some importants were measle, 10.1% of total subjects; meningitis, 7.3%; convulsion with some reasons, 4.9%; poliomyelitis. 3.2%; encephalitis, 2.4%; and mumps, rubella, pertusis, scarlet fever, and small pox were somewhat played a role in. Among 59 cases with train diseases, 53 were concussion by the accidents, such as traffic and falling or sliping down etc., the cerebral paralysis and hydrocephalus were two, respectively. And the blood diseases were severe newjaundice in all five cases. If we were summarized with the above mentioned, most of the hearing impairments were introduced by the combined reasons with familial or hereditary factors and the acquired, than by a simple disease. Among the congenital or hereditary hearing impairments classified to now a day, we suppose that the many cases with the acquired causes during pregnancy, delivery and after birth were complexed. Subsequently, the maternal and child health should be more and more developed in our country, also.

  • Objectives : This study aimed to investigate the toxic effects of chromium (VI) on the placental function and reproduction in rats. For the study, the placental prolactin-growth hormone (PRL-GH) gene expression, placental trophoblast cell differentiation and reproductive data were analyzed. Methods : The pregnancies of F344 Fisher rats were checked by the presence of a copulatory plug or sperm in the vaginal smear, which was defined as day 0 of the pregnancy. Pregnant rats were divided into the three groups. The control group was given tap water (chromium level < 0.001 ppm) and the remaining groups were given 250 or 750 ppm of chromium (VI) [as potassium dichromate], from day 7 to 19 of the pregnancy. Rats were sacrificed at days 11 and 20 of pregnancy. The mRNA levels of PRL-GH and Pit-1a and b isotype genes were analyzed by Northern blot hybridization and reverse transcription-polymerase chain reaction (RT-PCR). The hormonal concentration was analyzed by radioimmunoassay, and the differentiation of placental trophoblast cells were observed by histochemical studies. Reproductive data, such as placental and fetal weights, pregnancy period, and litter size, were surveyed at day 20 of pregnancy and after birth. A statistical analysis was carried out using the SAS program (version 8.1). Results : The mRNA levels of the prolactin-growth hormone (PRL-GH) family of genes were dose dependently reduced by chromium exposure. The mRNA levels of Pit-1a and b isotype genes that induce the expression of the PRL-GH family of genes were also reduced by chromium exposure. The PRL-GH hormonal concentration in the rat placenta, fetus and maternal blood were decreased by chromium exposure. In the middle stage of pregnancy (day 11), a high dose of chromium suppressed the differentiation of spongiotrophoblast cells that secret the PRLGH hormones. In the last stage of pregnancy (day 20), a high dose of chromium induced apoptosis of placental cells. Reproductive data, such as placental and fetal weights, litter size, were reduced, but the pregnancy period was extended in the group exposed to chromium compared with the controls. Conclusion : Chromium (VI) disrupts the ordered functions of the placenta, which leads to reproductive disorders in rats.

  • In recent, the roles of oleic acid, most abundant fatty acid in myelin, were investigated in relation to the brain functions. This study examined the effects of diets either with desirable ratios of $\omega$6/ $\omega$9 and P/M/S (mixed oil-fed group: MO) or with defficient in $\omega$3 series fatty acids (safflower oil-fed group: SO) on the oleic acid composition in RBC and brain synaptosomal, mitochondrial & microsomal phospholipids. The desirable fatty acid composition was computer-searched with different fats and oils to meet right ratios of both $\omega$6/ $\omega$3 and P/M/S. Diets were fed 3 weeks before conception and new-born pups were fed maternal milk from the same mothers and same diets until 9 wks of age. At 3 wks of age, the compositions of oleic acid in brain subcellular fractions and red blood cells were constantly remained whatever the composition of dietary fatty acids. But at 9 wks of age, the composition of oleic acid in synaptosome and mitochondria were significantly higher in MO group than SO group. The composition of oleic acid in milk was significantly higher in MO group than SO group, but in case of SO group, that of oleic acid was increased by 48%, in comparison with dietary fatty acid compositions. -9 desaturase index (18:0\longrightarrow8:1) of brain synaptosome was significantly higher in MO group than SO group at 3 and 9 weeks of ages, but that of brain microsome was higher in SO group than MO group at 9 wks of age. Taken together, the presences of oleic acid in the diet was important to maintain brain functions. The origins of oleic acid in brain may suggests two hypotheses; first, the central nervous system has priority for the uptake of oleic acid, and second the nervous system can synthesize all the oleic acid it needs, independently of its presence in the diet.

  • Nutritional anemia is an important nutritional problem affecting large population groups in most developing countries. Nutritional anemia is caused by the absence of any dietary essential involed in hemoglobin formation or by poor absorption of these dietary components. The most likely causes are lack of dietary iron, and folate, vitamin $B_{12}$ and high qualify protein. Anemia is considered to be a late mainfeastation of nutritional deficiencies, and even mild anemia is not the earilest sign of such a deficiency. Therefore, the object of therapy is to correct underlying deficiency rather than merely its manifestation. Iron deficiency anemia is generally much the most common form of anemia. And it is very prevalent particularly in pregnant women and young children, especially under five year of life. According to the rapid growth rate of infants, dietary iron should he provided for infants over three months of age in adequate amounts for the synthesis of hemoglobin required by the increasing blood volume and for the demands of newly formed cells. The principal causes of iron deficiency anemia are an inadequate dietary iron content, interference with absorption of iron from the intestine, excessive losses of iron from the body, disturbance of iron metabolism by infection, and social and cultural environments. The present study is planned to obtain informations concerning nutritional anemia through anthropometric and biochemical determinations for the assessment of nutriture in pre-school children. Determination was taken in 226 pre-school children in ruraI arae in 1968, 122 pre-school children in 1970, and 1526 hospitalized pre-school children in 1970. The results of this study are as follows; (1) According to Iowa Malnutrition Borderline (85 percentile) for weight, the proportions of underweighed pre-school boys and girls in rural area were 47.2% and 46.2% in1968, and were 36.1% and 51.8% in 1970. According to Iowa Malnutrition Borderline for height, the proportions of underheight boys and girls in rural area were 30.5% and 33.7%, and were 26.2% and 21.8% in 1970. Malnutrition scores of underweight for height values of boys and girls in rural area were 19.3 and 17.3 in 1968, and the scores of boys and girls were 15.6 and 15.5 in 1970. (2) The mean hemoglobin values of boys and girls in rural area were $11.2{\pm}1.8g/100ml\;and\;11.4{\pm}1.6g/100ml$ in 1968. In 1970, the mean values of boys and girls in rural area were $11.3{\pm}1.3g/100ml\;and\;11.7{\pm}2.4g/100ml$. The mean hemoglobin values of hospitalized boys and girls were $11.9{\pm}2.2g/100ml\;and\;11.7{\pm}2.4g/100ml$ in 1970. It is found that 92 of 215 children (42.7%) in rural area had concentrations of hemoglobin less than 11.0g/100ml in 1968. In 1970, 55 of 121 children (45.4%) in rural area and 559 of 1526 hospitalized children (36.6%) had concentrations of hemoglobin less than 11.0g/100ml. (3) The mean hematocrit levels of hospitalized boys and girls were $35{\pm}26.8%\;and\;35.4{\pm}6.4%$ in 1970. And 443 of 1334 hospitalized children (33.2%) had hematocrit values below 33%. (4) The average mean corpuscular hemoglobin concentration levels of hospitalized boys and girls were $32.4{\pm}2.2\;and\;32.3{\pm}2.2$ in 1970. And 1016 of 1352 hospitalized children (75.1%) had the mean corpuscular hemoglobin values below 34. (5) The mean iron values of young children in rural area and hospitalized children were $62.0{\pm}6.3{\mu}g/100ml\;and\;60.7{\pm}22.8{\mu}g/100ml$. The proportions of anemia cases below $50{\mu}g/100ml$ in rural area was 37.9%, and 34.3% in hospitalized children. (6) The mean total iron binding capacity of young children in rural area was $376{\pm}57.88{\mu}g/100ml,\;and\;342.2{\pm}6.15{\mu}g/100ml$ in hospitalized children. (7) The average transferrin saturation percentage of young children in rural area was $16.9{\pm}4.7%,\;and\;18.0{\pm}8.4%$ in hospitalized children. The proportions of anemia cases below 15% of young chi1dren in rural area and hospitalized children were 48.3% and 41.2%. Therefore, authors wish to recommend that the following further studies should be undertaken: (1) Standardization of simplied laboratory examination of nutritional anemia. (2) The prevalence of nutritional anemia and the requirements of iron, folate, and vitamin $B_{12}$ of pre-school children. (3) The content and absorption of iron in Korean food. (4) The pathogenesis of nutritional anemia and prevention of parasitic disease. (5) Maternal health and nutrition education.

  • Purpose : Preeclampsia is a major cause of maternal and perinatal mortality and morbidity and is considered to be a multifactorial disorder involving a genetic predisposition and environmental factors. Endothelin-1 (ET-1) is a potent vasoconstrictor peptide, and alterations in the ET-1 system are thought to play a role in triggering the vasoconstriction seen with preeclampsia. The aim of this study was to examine the frequency of the 4 common single-nucleotide polymorphisms (SNPs) (c.1370T>G, c.137_139delinsA, c.3539+2T>C, and c.5665G>T) of the ET-1 gene in normotensive and preeclamptic pregnancies and to investigate whether these SNPs are associated with preeclampsia in pregnant Korean women. Methods : We analyzed blood samples from 206 preeclamptic and 216 normotensive pregnancies using a commercially available SNapShot kit and an ABI Prism 3100 Genetic analyzer. Results : There were no significant differences in genotype or allele frequencies of the 4 SNPs in the ET-1 gene between preeclamptic and normotensive pregnancies. The respective frequencies of the 3 haplotypes (TDTG, GDCT, and TICT; >10% haplotype frequency) were 61%, 13% and 13%, respectively, in preeclampsic pregnancies and 62%, 14% and 12%, respectively, in normotensive pregnancies. The frequencies of these haplotypes were similar for both groups. Using multiple logistic regression analysis, we did not observe an increase in the risk of preeclampsia for the 4 SNPs of the ET-1 gene under either a recessive or dominant model. Conclusion : This study suggests that the 4 SNPs of the ET-1 gene are not associated with an increased risk for preeclampsia in pregnant Korean women.
