Objectives: Antivenom serums have been used extensively for over a century and are the only effective treatment option for snake bites and other dangerous animal envenomations. In therapeutic serum centers, a wide range of antivenoms is made from animal serum, mainly equine and sheep, that are immunized with single or multiple venoms. This work aimed to use caprylic acid (CA) to purify therapeutic snake antivenom. Methods: Plasma was obtained from equine immunized with a mixture of venoms. Immunized plasma was obtained by precipitation of different concentrations (2-5%) of CA. This methodology was compared to that based on ammonium sulfate (AS) precipitation. Sediment plasma proteins were purified by ion-exchange chromatography. Protein assay, SDSPAGE, and agar gel diffusion were performed. Results: The total protein precipitation with AS was higher than precipitation with CA, but the best results were obtained when CA was added to the plasma until a final CA concentration of 5% was reached. Chromatography and electrophoresis indicated a stronger band for the 5% CA, and the gel diffusion assay showed antigen-antibody interaction in the purified serum. Conclusion: The use of CA compared to the routine method for purifying hyperimmune serums is a practical and cost-effective method for preparing and producing therapeutic serums. It constitutes a potentially valuable technology for alleviating the critical shortage of antivenom in Iran.

This study was to investigate the effect of zinc supplementation on serum cholesterol concentration of young women. Thirty healthy students were divided into Zn and placebo groups, and were orally given with zinc(50mg/day, 220mg as ZnSO4·7H2O) or placebo for 2 month (June 9-August 7, 1988). Changes of plasma zinc, serum total cholesterol, HDL-cholesterol (HDL-C), LDL-cholesterol(LDL-C) and total lipid were analyzed from the initiation to 1 month after the end of zinc supplementation at monthly interval. Plasma zinc, serum LDL-C content and LDL-C/HDL-C were significantly increased by zinc supplementation. Serum total cholesterol content tended to be increased by zinc supplementation but was not significantly different between the two groups. Serum HDL-C content was significantly decreased by zinc supplementation. Serum total lipid content was not different between the two groups during experimental period. Thus, in this study considering the effect of zinc supplementation on serum cholesterol concentration, we conclude that the effect of zinc supplementation on coronary heart disease may be negative.

This study investigated that the antioxidative effect of freeze-dried cranberry powder against protein and lipid oxidation and ameliorative effect of serum lipid profile in rat fed atherogenic diet. Six weeks old male Sprague-Dawley rats were divided into the following four groups: normal diet group with 5% com oil(control), atherogenic diet group with 5% com oil, 10% lard, 1% cholesterol, and 0.5% sodium cholate(HFC), atherogenic plus 2% cranberry powder diet group(HFC+C2), and atherogenic plus 5% cranberry powder diet group(HFC+C5), and respective diet and water were fed daily for 6 weeks. After the experimental period, the serum lipid profile, such as total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride, ferric reducing ability of plasma(FRAP), plasma phenolics content, superoxide dismutase(SOD) activity, serum protein carbonyl and thiobarbituric acid reactive substances(TBARS) levels were examined. Total phenolic compound and total flavonoid levels in freeze-dried cranberry powder were 9.94 mg/g and 8.12 mg/g, respectively. Serum total cholesterol and LDL-cholesterol levels were not significantly different for cranberry powder treatment, but serum HDL-cholesterol level was significantly increased in HFC+C5 group compared with HFC group. Plasma FRAP value tended to be increased by cranberry powder treatment though there was no significant difference. Plasma total phenol concentrations and SOD activities were not significantly different among all groups. Serum protein carbonyl and TBARS levels were significantly decreased in HFC+C5 group compared with HFC group. Overall results suggested that freeze-dried cranberry powder might have the serum lipid improving effect, as well as anti oxidative effect demonstrated by its protective effect against protein and lipid oxidation.

The purposes of this research were to assess dietary fatty acid patterns and to elucidate the relationship between the serum cholesterol levels and dietary fatty acid patterns, plasma fatty acid compositions, BMI (body mass index), and other lipid profile. The subjects were 151 adults aged 23 to 80 years, selected from the Outpatient Clinic and Cardiova-scular Department of the Seoul Municipal Hospital. Dietary data were obtained using three day food records. Sixteen dietary fatty acids were analyzed using Korean and US nutrient databases. The subjects were divided into three serum cholesterol levels: desirable (< 200 mg/dl, N = 44), borderline-risk ($\geq$ 200 - < 240 mg/dl, N = 35), and high-risk ($\geq$ 240 mg/dl, N = 72) groups. The high-risk group had higher BMI, waist, and waist to hip ratio (WHR) than the desirable and borderline-risk groups. Serum concentrations of triglyceride, LDL cholesterol and LDL/HDL cholesterol ratio were significantly higher in the high-risk group as compared to those in the other two groups. The serum cholesterol levels were highly correlated with BMI (r = 0.435), triglyceride (r = 0.425) and LDL/HDL cholesterol (r = 0.870) ratio. The highest fatty acid intake was from oleic acid (33 - 34% of total fatty acid intakes), which was followed by linoleic acid (27%), palmitic acid (19%), and stearic acid (7%). There was no correlation between the serum cholesterol levels and the dietary fatty acid intakes, polyunsaturateumonounsaturateusaturated fatty acids (P/M/S) and $\omega$6/$\omega$3 ratios. The correlation between plasma fatty acids such as myristic acid, oleic acid, linoleic acid, and docosahexaenoic acid and serum cholesterol levels was also weak.

Objective: Growth hormone and its mediator, insulin-like growth factor-1 (IGF-1), have been suggested to exert gonadotropic actions in both humans and animals. The present study was conducted to assess the relationship between serum IGF-1 concentration, seminal plasma concentration, and sperm parameter abnormalities. Methods: A total of 79 men were enrolled in this study from December 2011 to July 2012 and were prospectively analyzed. Patient parameters analyzed included age, body mass index, smoking status, urological history, and fertility history. Patients were divided into four groups based on their semen parameters: normal (A, n=31), abnormal sperm motility (B, n=12), abnormal sperm morphology (C, n=20), and two or more abnormal parameters (D, n=16). Patient seminal plasma and serum IGF-1 concentrations were determined. Results: Patient baseline characteristics were not significantly different between any of the groups. The serum IGF-1 levels in groups B, C, and D were significantly lower than the levels in group A; however, the seminal plasma IGF-1 levels were not significantly different between any of the groups. Conclusion: Men with abnormal sperm parameters had significantly lower levels of serum IGF-1 compared with men with normal sperm parameters. Seminal plasma IGF-1 levels, however, did not differ significantly between the groups investigated here. Further investigations will be required to determine the exact mechanisms by which growth hormone and IGF-1 affect sperm quality.

The purpose of this study was to examine the effects of taurine supplementation on serum lipidperoxide(TBARS), a risk factor for cardiovascular disease. The subjects were 22 healthy middle-aged women(33 to 54 years). Serum lipids, thiobarbituric acid reactive substances(TBARS), and plasma taurine levels were measured before and after supplying 3 g of taurine per day for 4 weeks. Plasma taurine was analyzed by Dabsyl-Cl(4-dimethylamino azobenzen-4-sulfonyl-chloride) derivatization and reversed-phase HPLC. Serum TBARS was measured by the Yagi method. Daily dietary taurine intake was calculated by food frequency questionnaire method. The weight and height means of the 22 subjects were $57.9{\pm}5.2$ kg and $159.2{\pm}5.2$ cm, respectively. Their percent body fat and waist/hip ratio(WHR) were 26.8% and 0.84, respectively, which were slightly higher than the average for middle-aged Korean women. Serum TC, TG and LDL-C levels tended to decrease after taurine supplementation, but HDL-C was not changed. A positive correlation between plasma taurine and HDL-C was shown after taurine supplementation. The serum TBARS concentration was significantly decreased from $5.05{\pm}0.84nmol/d{\ell}$ to $4.17{\pm}0.64nmol/d{\ell}$ after taking taurine(p<0.01), and the plasma taurine concentration was significantly increased from $63.7{\pm}14.2{\mu}mol/{\ell}$ to $73.8{\pm}16.6{\mu}mol/{\ell}$ after taurine supplementation(p<0.05). The average dietary intake of taurine was $178.5{\pm}50.4$ mg/day, which is similar to the average daily taurine intake of Korean women. In conclusion, taurine is an effective nutrient that antagonizes TBARS levels. Therefore, this study suggests that a sufficient taurine intake may be an effective way to prevent cardiovascular disease such as atherosclerosis.

The ferrokinetics and red cell life spans of the patients with chronic glomerulonephritis were investigated by the double tracing method using radioactive iron ($^{59}Fe$) and chromium ($^{51}Cr$). According to the serum NPN levels, the patients were subdivided into 3 groups: Group 1. 6 patients, had the levels below 40 mg/dl Group 2. 6 patients, had the levels between 41 mg/dl to 80 mg/dl Group 3. 10 patients, had the levels above 80 mg/dl The results were as follows: 1) Red blood cell-, hematocrit- and hemoglobin values were moderately reduced in patients with normal serum NPN levels, while markedly reduced in patients with elevated serum NPN levels. 2) The plasma volume was increased, while the red cell volume was decreased in patients with elevated serum NPN levels, hence, total blood volume was unchanged. 3) The serum iron level was slightly reduced h patients of groups 1 and 2, while was within the normal ranges in patients of group 3. 4) i) In patients with normal serum NPN levels, the plasma iron disappearance rate, red cell iron utilization rate, red cell iron turnover rate, daily red cell iron renewal rate, circulating red cell iron and red cell iron concentration were within the normal ranges, while the plasma iron turnover rate was slightly reduced. ii) In patients with elevated serum NPN levels, the plasma iron disappearance rate was delayed, while the plasma iron turnover rate was within the normal ranges. The red cell iron utilization rate, red cell iron turnover rate and circulating red cell iron were decreased and the period in which the red cell iron utilization rate reachd its peak was delayed in Group 3 patients. The daily red cell iron renewal rate and the red cell iron concentration were unchanged. iii) The mean red cell life span was within the normal ranges in patients with normal serum NPN levels, while was shortened in patients with elevated serum NPN levels.

The purpose of this study was to examine the effect of electroanalgeia and $\beta-endorphin$ action by acupuncture-like (Lof/Hil) transcutaneous electrical nerve stimulation (TENS) applied to acupuncture points. Twelve healthy adult male aged between 19 ann 25 were randomly assigned to TENS group (n=6) and naloxone group (n=6). Subjects of both groups were strongly stimulated TENS with 4 pps and $200{\mu}s$ for 30 minutes on the LI 3 and LI 10 meridian points of dominant am. Naloxone group was injected naloxone hydrochloride before TENS application. The experimental pain threshold was measured by chronaxie meter CX-2 on the distal end of radius just before and after TENS application. The levels of plasma $\beta-endorphin$ and ACTH. serum cortisol and urinary 17-OHCS were analyzed by radioimmunoassay (RIA) kits before and after TENS application. In TENS group, there was a significant increase of experimental pain threshold (p<0.01), plasma $\beta-endorphin$ level (p<0.05), serum cortisol level (p<0,001) and urinary 17-OHCS levels (p<0.05) after TENS application. The plasma ACTH level was not significantly increased, but it showed an increasing tendency. In naloxone group, although there was a decreasing trend, ACTH and cortisol level did not show a significant change, but $\beta-endorphin$ and 17-OHCS level were significantly decreased (p<0.01). The result of this study stewed that acupuncture-like TENS induced analgesic effect, such that the levels of plasma $\beta-endorphin$, plasma ACTH, serum cortisol and urinary 17-OHCS were concomitantly increased with experimental pain threshold. It is suggested that the analgesic mechanism of the acupuncture-like TENS probably related to endogenous opioid component such as $\beta-endorphin$.

The changes of plasma renin activity, aldosterone concentration, serum sodium-, and potassium levels were studied before and after the water loading followed by diuretics injection. The materials were: 13 non-, 11 normal-, and 11 toxemic pregnancy cases. The plasma renin activity and aldosterone concentration of the cord and postpartum blood were also measured. Following were the results: 1. The plasma renin activity was elevated significantly in normal pregnancy, and slightly in toxemic pregnancy. The serum sodium levels were decreased in pregnancy. 2. The plasma aldosterone concentration was slightly decreased in normal pregnancy, and slightly increased in toxemic pregnancy, however, statistically insignificant. 3. The plasma renin activity of the cord and postpartum blood were lower than those of pregnancy cases. 4. The changes of plasma renin activity after the diuretic administration showed an initial increase, which recovered within 2 hours. These changes were the least in normal pregnancy, and the most in toxemic pregnancy. 5. The changes of plasma aldosterone concentration after the diuretic administration were similar to those of plasma renin activity, although the variations were not so wide.
