Effect of Burdizzor's bloodless castration on blood picture, serum transaminase activity and growth of Korean calves were observed for 90 days period on indoor feeding. The results obtained were as follows; 1. In complete blood count, hemoglobin, hematocrit, total leucccyte count were shown only little changes comparing with that of controls. 2. In diffenentiaI count, the lymphocytes were significantly decreased in first week following castration, while the neutophils were relatively decreased (with a relative lymphocytosis) in later period of experiment (2 to 12 weeks). 3. Serum transaminase(SGOT and SGPT) and alkaline phosphatase activities were not influenced by Burdizzor's bloodless castration. 4. On average total gain of body weight, no significant differences were found between castrated and noncastrated groups during the experimental period.

The Hexane Extract (HE) and Ethyl Acetate Soluble Fraction of the Methanolic Extract (EASFME) of the fruit pulp of Momordica dioica Roxb. (Cucurbitaceae) was evaluated for its anti-hepatotoxic activity in rats. Acute hepatotoxicity was induced by administering paracetamol (2 g/kg, p.o.) for 3 days. The extracts, at a dose of 400 mg/kg (p.o.) administered for 7 days exhibited a significant therapeutic effect by lowering Serum Glutamate Oxaloacetate Transaminase (SGOT), Serum Glutamate Pyruvate Transaminase (SGPT), Serum Alkaline Phosphatase (ALP) and Serum bilirubin and increasing the serum protein levels. These biochemical observations were supplemented by histopathological examination of the liver sections. The activity of extract was also comparable to the standard drug Silymarin, which is a well-known natural anti-hepatotoxic drug.

Currently convulsion is considered to be a chronic central nerve disease characterized by involuntary and severe muscle contraction or spasm. In many recent studies, convulsion's mechanism is due to unbalance between stimulation and suppression of the central nerve system, such as GABA and glutamic acid. Objectives : This study was performed to examine the anticonvulsant effects of Podam-hwan on brain GABA levels and glutamate content in picrotoxin-induced convulsions and to determine the inhibitory activity on GABA transaminase. Methods : Brain GABA levels and glutamate content in the brains of picrotoxin-induced mice using reverse phase HPLC method, anticonvulsant effect in vivo, and the inhibitory effect on GABA transaminase activity in vivo have been investigated. Results : Podam-hwan significantly lengthened the onset time of picrotoxin-induced convulsion at a concentration of 15mg/kg, but did not show a dose-dependent pattern. Also, Podam-hwan shortened the duration of convulsion by 52.2% at a dose of 30mg/kg in comparison with the control group. Podam-hwan inhibited dose-dependently GABA transaminase activity by 35.5% at 30mg/kg, comparing with the control gmup. Podam-hwan also increased the brain GABA level by 38.7% and 68.8% at doses 15mg/kg and 30mg/kg, respectively. In addition, Podam-hwan decreased the brain glutamate level by 9.6% and 17.8% at doses 15mg/kg and 30mg/kg, respectively. Conclusions : Podam-hwan can be prescribed for the treatment of convulsion by enhancement of brain GABA level and inhibition of GABA transaminase activity.

This study was performed to evaluate the biological activity and protective effect of Cassia tora ethanol extracts against D-galactosamine induced hepatotoxicity in rats. Male Sprague-Dawley rats were grouped into normal group, D-galactosamine treated group(control), D-galactosamine plus 0.25% Cassia tora extracts treated group and D-galactosamine plus 0.5% Cassia tora extracts treated group. Normal and control group were fed control diet and Cassia tora extracts treated groups were fed experimental diets containing 0.25% or 0.5% Cassia tora ethanol extracts for 5 weeks. Body weight gain and liver weight of rats were not significantly different between groups. Cholesterol and triglyceride concentrations in serum and liver were significantly lower in rats treated only with D-galactosamine compared to normal group, and improved in Cassia tora extracts supplemented rats. D-galactosamine treatment significantly increased serum aspartate transaminase, alanine transaminase, gamma glutamyl transferase and alkaline phosphatase, however, the activities of aspartate transaminase and alanine transaminase were significantly decreased in Cassia tora extracts supplemented rats when compared with D-galactosamine treated control group. Cassia tora extracts significantly suppressed the D-galactosamine-induced elevation of liver thiobarbituric acid reactive substances(TBARS) contents. Superoxide dismutase activity was decreased by D-galactosamine treatment, however by the supplementation of Cassia tora ethanol extracts, significantly increased in dose-dependent manner. Glutathione peroxidase activity in rats fed diets containing Cassia tora extracts was decreased compared to control. Based on these results, we concluded that Cassia tora ethanol extracts may prevents the D-galactosamine-induced hepatotoxicity probably via an antioxidant mechanism.

Obesity, a state of having excessive body fat enough to attack one's health, is most blamed for causing chronical degenerative illness such as hypertension, diabetes mellitus as well as arteriosclerosis. According to many studies, the program for the weight control was the most demanded at the worksites. This study was designed to investigate the correlation between the degree of obesity and blood parameters of the employees at the worksites. The results of periodic medical examination for 571 employees(male: 418, female: 153) were analyzed; Age, BMI, systolic blood pressure(SBP), diastolic blood pressure(DBP), hemoglobin(Hb), fasting blood sugar(FBS), total-cholesterol(TC), serum glutamic oxaloacetic transaminase (sGOT), serum glutamic pyruvic transaminase(sGPT) and $gamma$-glutamyl transpeptidase($gamma$-GTP). Pearson correlation coefficient was used to find out the correlation between BMI and each blood parameters. In the case of male, 27.3% of the subjects were over-weight. The subject's age and their blood levels of uric acid, FBS, sGOT and sGPT did not show any significant difference regardless of BMI's, while SBP, DBP, Hb, TC and $gamma$-GTP levels of the overweight group were significantly higher than those of normal group. In the case of female, 9.2% of the subjects were over-weight. This study shows that the implementation of weight control program is required at the worksites
