Anti-hepatitis effect of the olean-9(11),12-diene-3 b, 30-diol 3 b, o-hemisuccinate Na Salt (III b), a glycyrrhetinic acid derivative, was studied in CCl4 induced mouse. The mouse was administered i.p. with 0.1 mole/kg or 0.2 mole/kg of III b, then followed by 31.4 microliters/kg of CCl4. III b was shown to promote the activity of the glucose-6-phosphatase, lower the content of malondialdehyde, and prevent the activity from the soluble enzyme(i.e. GPT, GOT, LDH) from flowing out in the serum enzyme and liver homogenate. III b had the similar anti-peroxidation effect as vitamin E and can maintain the liver function.

The effectiveness of the antioxidant thiol, N-acetylcysteine (NAC), in enhancing methylmercury (CH3HgCl) excretion and its utility as a possible antidote in CH3HgCl poisoning has been reported. NAC, however, has been reported to be ineffective in accelerating excretion of divalent toxic metals, including inorganic mercury, Hg2+. In this study, we evaluated the possible protective effect of short-term pretreatment with NAC against mercuric chloride (HgCl2) toxicity in rat model. This is aimed at determining its chemopreventive or prophylactic benefit in situations of high risk exposure (occupational/industrial) to mercury. Rats were divided into three treatment groups. Group I received saline (10 ml/kg) and served as control. Group II received HgCl2 (5mg/kg) and group III received NAC (10mg/kg) plus (5mg/kg). All administration was via intraperitoneal (i.p.) injection. Saline and NAC were administered for 5days and HgCl2 was administered to rats in groups II and III on the 5th day. Animals were sacrificed 24 hours after HgCl2 injection and samples obtained for biochemical evaluation. Results revealed that single i.p. injection of HgCl2 induced significant renal oxidative damage resulting in significant decrease in the activities of superoxide dismutase (SOD), catalase (CAT), glutathione-s-transferase (GST), depletion of reduced glutathione (GSH) and increase in malondialdehyde (MDA) levels in these rats. The activities of glucose-6-phosphatase (G6Pase) and 5'-nucleotidase (5'-NTD) (markers of microsomal damage) also decreased in these HgCl2 treated rats. The oxidative damage induced by HgCl2 led to significant alterations in renal histology and caused functional impairment (indicated by elevated blood urea nitrogen (BUN) and serum creatinine) in these rats. NAC was effective in attenuating the oxidative damage, functional impairments and histopathological changes that characterized HgCl2 intoxication in this study. Renal antioxidant defense system was re-enforced by NAC, leading to increase in the activities of SOD, CAT, GST and decreases in GSH depletion and MDA level. Our results therefore reveal the ameliorative effect of NAC pretreatment against HgCl2 toxicity in vivo, thus, suggesting its usefulness as a possible chemoprophylactic agent during occupational or industrial exposure to inorganic mercury.

The effects of in ovo feeding (IOF) of creatine pyruvate (CrPyr) on the hatchability, growth performance and energy status of embryos and broilers (Arbor Acres) were investigated. Five treatments were arranged as non-injected treatment (Control), 0.6 ml physiological saline (0.75%) injected treatment (Saline), and IOF treatments injected with 0.6 ml physiological saline (0.75%) containing 3, 6 or 12 mg CrPyr (CrPyr3, CrPyr6 or CrPyr12) into the amnion per fertile egg on day 17.5 of incubation. After hatching, 80 male chicks from each treatment with similar weight close to the average BW of their pooled group were selected and randomly assigned into eight replicates of 10 chicks each. The results showed that the hatchability was not affected among groups, whereas the hatching weight of broilers in CrPyr12 was significantly higher than the control and saline groups (P0.05). Irrespective of dosage, the concentrations of creatine and phosphocreatine, and activities of creatine kinase in embryos were enhanced in CrPyr treatments at 19 E when compared with the control and saline groups (P<0.05). The activities of glucose-6-phosphatase in liver in CrPyr6 and CrPyr12 treatments were higher than the control and saline groups at 19 E (P<0.05). In conclusion, these results indicated that IOF of CrPyr, especially at the level of 12 mg/egg, could improve energy status of embryos and hatchlings, which was useful for enhancing hatching weight, BW and pectoral muscle weight until the end of the experiments at 21 days post-hatch in broilers.
