Background: Children with cleft lip and/or palate can be undernourished due to feeding difficulties after birth. A vicious cycle ensues where malnutrition and low body weight precludes the child from having the corrective surgery, in the absence of which the child fails to gain weight. This study aimed to identify the proportion of malnutrition, including the deficiency of major micronutrients, namely iron, folate and vitamin B12, in children with cleft lip and/or palate and thus help in finding out what nutritional interventions can improve the scenario for these children. Methods: All children less than 5 years with cleft lip and/or cleft palate attending our institute were included. On their first visit, following were recorded: demographic data, assessment of malnutrition, investigations: complete blood count and peripheral blood film examination; serum albumin, ferritin, iron, folate, and vitamin B12 levels. Results: Eighty-one children with cleft lip and/or palate were included. Mean age was 25.37±21.49 months (range, 3-60 months). In 53% of children suffered from moderate to severe wasting, according to World Health Organization (WHO) classification. Iron deficiency state was found in 91.6% of children. In 35.80% of children had vitamin B12 deficiency and 23.45% had folate deficiency. No correlation was found between iron deficiency and the type of deformity. Conclusion: Iron deficiency state is almost universally present in children with cleft lip and palate. Thus, iron and folic acid supplementation should be given at first contact to improve iron reserve and hematological parameters for optimum and safe surgery.

A one-year-old spayed female Korean Shorthair cat presented to Kangwon National University Veterinary Hospital with vomiting, weight loss, lethargy, loss of appetite, and polyuria that lasted for more than two weeks. The body condition score, blood pressure, heart rate, and body temperature were abnormally low, and the physical examination findings were consistent with moderate dehydration. Hematological and biochemical tests demonstrated mild azotemia and a low Na:K ratio. Additional abdominal ultrasound imaging revealed reduced size of both adrenal glands. The adrenocorticotropic hormone (ACTH) stimulation test showed decreased post-ACTH cortisol and aldosterone levels and increased endogenous ACTH levels, confirming a diagnosis of primary hypoadrenocorticism. The cat was treated with subcutaneous injections of desoxycorticosterone pivalate (DOCP) and oral prednisolone supplementation, and subsequent electrolyte analysis showed a normal Na:K ratio. Clinical symptoms were also improved in response to treatment. Hypoadrenocorticism in cats is a very rare disease, but it should not be excluded as a potential diagnosis in favor of kidney diseases or other conditions, especially when the Na:K ratio is low. In addition, the prognosis for the disease and the response to DOCP treatment should be further evaluated in cats.

The subchronic toxicity of a combined preparation of ticlopidine and ginkgo biloba extract (EGb 761) mixed in a ratio of 10: 4 was examined in male and female Sprague-Dawley rats. Rats were treated with the test substance at a dose of 52 mg/kg, 156 mg/kg, or 467 mg/kg intragastrically for 30 consecutive days. Control rats were treated with vehicle only. Each group consisted of 10 rats. No death or abnormal clinical signs were observed throughout the administration period. A transient decrease in body weight gain and food intake was observed in the rats treated with the high dose (467 mg/kg), which was recovered to normal in a week. There were no drug-related differences in urinalysis and hematological results. A significant increase in serum total cholesterol and total protein was observed in both sexes of the rats treated with a dose of 467 mg/kg daily, but all the other values obtained in serum chemistry appeared to be within normal range. A dose dependent increase in liver weight was observed in both male and female rats. Relative kidney weight was also increased in the high dose groups. There was no gross pathological finding at terminal sacrifice. Microscopic histopathological examination did not show any lesion in terms of correlation with administration of the test substance. The results suggest that under the conditions employed in this study no observable effect level (NOEL) of the test substance be 52 mg/kg/day.

Toxicity of a combined preparation of ticlopidine and ginkgo biloba extract (EGb 761) in a ratio of 10: 4 was examined in male and female Sprague-Dawley rats. Rats were treated with the test substance intragastrically at a dose of 0 mg/kg, 17 mg/kg, 52 mg/kg or 156 mg/kg for 91 consecutive days. No death or abnormal clinical sign was observed throughout the administration period. There was no difference in body weight gain, food intake or water consumption among different dose groups. Test sub-stance-related differences were not observed in urinalysis. In hematological results mean corpuscular hemoglobin (MCH) of low and high dose male group was increased. Prothrombin time of medium and high dose female group was decreased. A significant increase in serum total cholesterol was observed in both sexes of rats treated with a daily dose of 156 mg/kg, but all the other values obtained in serum chemistry appeared to be within normal ranges. A dose dependent increase in the relative liver and kidney weights was observed in both male and female rats. There were no gross pathological findings at terminal sacrifice. Microscopic histopathological examination did not show any lesion associated with administration of the test substance. The results suggest that under the conditions employed in this study no observable effect level (NOEL) of the test substance be greater than 17 mg/kg/day, but less than 52 mg/kg/day.

This sutdy was carried out to investigate the acute toxicity and foru-week intravenous toxicity of the intralipidos in rats and rabbits. The acute toxicity study of Intralipidos was performed in Spragur-Dawley (SD) rats. Intralipidos was administered by intravenous to maximum dose 200 ml/kg. $LD_{50}$ of intralipidos was found 139.5ml/kg and 153.8ml/kg in male female SD rats. Four-week toxicity of intralipidos using New Zealand White Rabbit and SD rats. The Rabbit and Rats were administered by intravenous seven days per week for 28 days, with dosage of 15, 6, 2 ml/kg/day and 20, 6, 2ml/kg/day, respectively. Animals treated with intralipidos did not cause any death and show any clinical signs. They did not show any significant changes of body weight, feed uptake and water consumption. They were not significantly different from the control group in urinalysis, ocular examination hematological, serum biochemical value and histopathological examination. Therefore, Intralipidos was not indicated to have any toxic effect in the Rabbits and Rats, when it was administrated by intravenous below the dosage 15ml/kg/day and 20 ml/kg/day for four weeks.

Objectives : This study was designed to investigate the effects of Sunbanghwalmyung-eum gamibang on Monosodium iodoacetate-induced osteoarthritis rats. Methods : Forty Sprague-Dawley (SD) rats were divided into 5 groups of 8 rats each. Osteoarthritis (OA) was induced by injecting MIA (2 mg/50 µl) into the joint cavity of the left knee of SD rats belonging to the experimental group, and normal saline was injected into the joint cavity of the left knee instead of MIA in the normal group. To the normal group and the controlled group (OA group), 2 ml of distilled water was orally administered. To the positive control group (Indomethacin group), indomethacin 2 ml at a concentration of 2 mg/kg, to the low concentration group of SHG (Low group), 2 ml of SHG at a concentration of 2 mg/kg, and to the high concentration group of SHG (High group), 2 ml of SHG at a concentration of 4 mg/kg ml was orally administered. The drug was administered for a total of 4 weeks, and histological changes were analyzed by Hematoxylin-Eosin staining and Safranin-O staining. In addition, inflammatory cytokines such as TNF-α, IL-1β, and IL-6, and MMP-13, TIMP-1, and GAGs were immunohistochemically analyzed. Finally, hematological examination, blood biochemical examination, and liver and kidney biopsy were performed. Results : SHG groups (Low and High) inhibited the matrix destruction and damage of the knee joint cartilage in SD rat model, and significantly prevented the reduction in cartilage thickness. In SHG groups, the expressions of TNF-α, IL-1β, IL-6 and MMP-13 were significantly decreased, and the expressions of TIMP-1, GAGs were significantly increased compared with OA group. The safety indicators had no significant differences among five groups. Conclusions : These results show that SHG has cartilage protection capacity, anti-inflammatory effect.
