Objectives This study is designed to evaluate the relationship between school life maladjustment and oriental medicine by diagnostic procedure based on the symptoms of weak children. Methods The questionnaire administrated to 130 fifth grade elementary school students in Daejeon was analyzed. Results 1. Comparing and analyzing different sexes in terms of school adjustment grades, girls were more adaptable than boys. 2. Weak score didn't show significant difference in sex and in the school adjustment 3. Based on the relationship between a group normal children and a group of children with weak lung, normal children group was more adaptable than group of children with weak lung. Conclusions School life maladjustment should be investigated as a new field of oriental medical treatment and further study needs to be done.

The single oral toxicity of JG-381 was studied in Sprague-Dawley rats of both sexes. In this study, rats were administrated orally with dosages of 267, 400, 600, 900 and 1350 mg/kg of JG-381. We daily examined number of deaths, clinical signs, body weights and gross findings for 14 days after JG-381 administration. When we administered different doses of 267, 400, 600, 900 and 1350 mg/kg, we found 1, 4, 4, 5 and 5 male rats died and 3, 5, 4, 5 and 5 female rats died within 1 day after administration, respectively. Some clinical signs (decrease locomotor activity, salivation, soft stool, prone position, lacrimation, crouching position, convulsion, ataxic gait, incontinence of urine) were also observed during the experimental period. Our findings suggest that oral L $D_{50s}$ (95% confidence limit) for male and female rats are 327 mg/kg (270~396 mg/kg) and 250 mg/kg (256~264 mg/kg), respectively.y.

Fingerprints of 100 New Zealand-Samoan males and 93 females have been analyzed. Whorls are more numerous in fingerprint females (65.6%) than in males (55.6%). The index of pattern intensity displays a higher value in females (16.49) than in males (15.48). The bimanual differences both in males and females are not statistically significant for the occurrence of patterns on the digits of the right and left hands. Also the difference between both sexes for the occurrence of patterns is not statistically significant. Incidences of actual symmetry on homologous digits represented 78.2% in males and 85.8% in females. The mean total ridge counts showed $175.7{\pm}54.6$ ($M{\pm}SD$) in males and $171.6\{pm}49.8$ ($M{\pm}SD$) in females, respectively. Conclusively, this study shows that the New Zealand-Samoans are closely related to the Mongoloids in quantitative dermatoglyphics.

The most recent, Jeong and Nakabo (1997) described Raja koreana as a new species based on an adult female specimen collected from the southwestern coast of Korean Peninsula. Raja koreana has several unique characters not shared with any other supraspecific taxa of Rajoidei, but it was provisionally included in the genus Raja because of having no information of its clasper. Later, two mature males and a few specimens of the species were collected from near the type locality. Therefore, a new genus should be erected for this species. The new genus is characterized by the followings: Rostral shaft straight, narrow and thick in depth: unsegmented base with filamentous cartilage. Dorsal surface of tail with a row of distinct thorns along midline, patches of distinct thorns anterior to first dorsal fin and between first and second dorsal fins in bathe sexes; most thorns directed anteriorly, and thornlets directed posteriorly. Scapulocoracoid comparatively short and high, rear corner high, without anterior bridge, postventral fenestra expanded. Distal tip of accessory terminal 1 claspser cartilage well separated from the tip of accessory terminal 2 clasper cartilage.

Acute oral toxicity of Bifidobacterium breve K-110, Bifidobacterium breve K-111, Bifidobacterium infantis K-525 were studied in Sprague-Dawley rats of both sexes. In this study, we examined number of deaths, clinical signs, bod weight and gross findings for 14 day after single oral administration of B. breve K-110,B. breve K-111 or B. infantis K-525 with different levels. They did not show any toxic effect in rats and oral LD$_{50}$ value was over 5 g/kg in rats.s.

The acute toxicity of recombinant human epidermal growth factor, DWP-401 was evaluated in ICR mice of both sexes. Six groups of mice were administered orally or subcutaneously with 0, 0.125, 0.25, 0.5, 1 and 2 mg/kg of DWP-401. Abnormal clinical signs related to the compound were not observed, and no deaths occurred. Gross findings of necropsy revealed no evidence of specific toxicity related to DWP-401. LD$_{50}$ values for both male and female mice were evaluated to be over 2 mg/kg, which is approximately 2, 000 fold of presumed clinical dose.e.

A preliminary survey of Sarcocystis species in the slaughtered cattle in Seoul was undertaken during October through December 1987, using digestion diagnostic technique for the heart muscle specimens digested in 0.5% trypsin solution. Results indicated that 41.5% of 159 bovine hearts were infected with Sarcocystis proliferative forms. High frequencies in the exotic dairy cattle(42.2%) and the Korean native cattle(41.7%) were noticed in comparison with low frequency in the cross breed(25.0%). No differences were indicated between the sexes of the host animals, although an age difference was noticed as 48.9% in cattle older than four years in comparison with 39.0% and 37.1% in younger than two years and in two to four years, respectively.

임상적으로 건강한 진도개 203두의 혈액치(血液値)를 조사(調査)하였다. 203두에는 암수가 다 포함되어 있었으며 개의 연령은 3개월에서 10세까지 이었다. 적혈구수(赤血球數), 혈색소량(血色素量), 적혈구용적(赤血球容積) 그리고 호산구수(好酸球數) 등은 개의 연령과 함께 증가하였다. 진도개에서 나타난 높은 호산구수(好酸球數)는 심장사상충증(心臟絲狀蟲症)과 벼룩의 감염에 의한 피부염(皮膚炎)때문인 것으로 생각된다.

Sixty eight wild rats, Rattus norvegicus, were caught from Seoul city, Kyonggi, Kangwon, Cholla, and Kyongsang-provinces. All sera collected from rats were examined by immunofluorescent test to find antibody against murine typhus. The antibody prevalance to murine typhus was 4.4%(3/68). Sero-positive rate was 12.5%(2/16) in Kyonggi province and 12.5%(1/8) in Cholla province. The sero-positive rate difference between sexes of rats was not recognized. Three Rattus norvegicus having antibody to murine typhus were morphologically classified as subadult with 8.3%(1/12), middle-aged adult with 5.9%(1/17), and old adult with 4.8%(1/21), respectively.

The objective of this study is to collect basic data about sex bias in intrahousehold food distribution, by investigating 124 housekeepers living in Seoul . This Survey was performed using questionnaire about the experience of male-female dietary disparity and the attitudes about sex-differential nutrition Results were summarized as follows ; 1. 38% of housekeepers had been experienced in male-female disparity of food distribution at meal time in her childhood. Protein foods(meats & fishes) and special foods were not distributed evenly to both sexes. 2. The major causes of these unbalanced, sex-differential food distribution was rather masculine priority than food shortage. 3. Compared with the past, male-female dietary disparity was disappeared. However, 47.7% of housekeepers took more care for son's meals than daughter's, consciously or unconsciously.
