Effects of calcium soap of rice bran oil fatty acids supplementation alone and with DL-α-tocopherol acetate in lamb diets on performance, digestibility, ruminal parameters and meat quality.

Thirty-six Malpura lambs (28 day old and 6.7 ± 0.25 kg BW) were distributed equally in three groups having six males and six female. They were ad libitum fed individually three different experimental diets containing calcium soap of fatty acids (CA-FA) at 0 (T1 ) and 40 (T2 and T3 ) g/kg concentrate up to six months of age. Animals in T3 were supplemented additionally with 40 mg DL-α-tocopherol acetate/kg of concentrate. The roughage moiety included ad libitum dry Prosopis cineraria and fresh Azadirachata indica leaves. All the lambs were allowed to suckle from their dam up to weaning (90 day of age). Supplementation of Ca-FA improved weight gain and feed conversion ratio during both pre- (28-90 days) and post-weaning (91-180 days) phases; however, no effect of DL-α-tocopherol was observed. Metabolic parameters during post-weaning phase revealed non-significant effect on digestibility but improved nitrogen balance in the test groups. The effect on biochemical attributes did not show any significant alteration in ruminal parameters, blood biochemicals and urinary purine derivatives. Carcass traits revealed higher (p < 0.05) dressing yield and loin eye area with Ca-FA supplementation. The value of thiobarbituric reactive substances for nuggets prepared from frozen carcasses revealed significant (p < 0.05) reduction in T3 compared to the other dietary groups. Fatty acid profile of adipose tissue revealed higher (p < 0.001) 9-octadecanoic, 9-12-octadecadienoic, polyunsaturated fatty acids (PUFA), higher ratio of PUFA/saturated fatty acids (SFA), ω-6/ω-3 and lower SFA in Ca-FA-supplemented groups. It is concluded that supplementation of 40 g/kg calcium soap prepared from industrial grade rice bran oil in lamb ration provided additional energy intake, improved N utilization, gain and feed conversion ratio besides improving dressing yield and meat quality with CLA enriched fatty acid profile. DL-α-tocopherol acetate when supplemented at 40 mg/kg feed reduced lipid oxidation of meat products thus improving its keeping quality.

Mandating audio-video recording of informed consent: are we right in enforcing this?

Medicines are the result of experimentation carried out in animals and humans. However, there are numerous instances in the history of medicine where humans were subjected to undue risks and abuses, requiring regulations for their safety. Idea of informed consent has found its presence in medical literature from the times of Hippocratic Oath propagating principles of '...never do harm to anyone' and physician directed care of patients. This was revived in post-world war II era in the form of Nuremberg code and the declaration of Helsinki in response to various debilitating experimentations done on prisoners in concentration camps and elsewhere. Complete information and voluntary participation forms the ethical tenets of these acts and the same has been reflected in various guidelines enacted worldwide, which are sufficient to make sure that patient consent is obtained in fair and just manner. Despite this, there have been undesirable lapses in the conduct of clinical trials. This situation worsens, when intentional lapses in conduct of trial hamper the ability of socially and economically disadvantaged communities in developing countries to make free and informed decision.

Effect of combining viscous fibre with lovastatin on serum lipids in normal human subjects.

OBJECTIVES: Soluble fibre supplements are recommended to reduce the levels of low-density lipoprotein cholesterol (LDL-C). Limited information exists on the interaction between fibre and hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins). The purpose of the present study was to evaluate the per se effect of psyllium (10 g/day) and lovastatin (20 mg/day) alone and in combination on serum lipids in normal human volunteers. METHODS: In a 4-week open label, randomised, parallel study, subjects were randomised to receive 20 mg of lovastatin, 10 g of psyllium or 20 mg of lovastatin plus 10 g of psyllium in evening daily. Levels of total cholesterol (TC), LDL-C, high-density lipoprotein cholesterol (HDL-C), TC/LDL-C ratio, LDL-C/HDL-C ratio and triglycerides were determined after 1, 2, 3 and 4 weeks of treatment. RESULTS: The study group comprised 36 adult, male subjects. All treatments were well tolerated, and after 4 weeks the mean LDL-C, TC and TG levels in the group receiving 20 mg of lovastatin plus 10 g of psyllium fell by 30.88%, 26.88% and 26.21% from baseline, compared with 24.78%, 19.55% and 32.88% in the group receiving 20 mg of lovastatin and 3.58%, 2.90% and 10.95% in the group receiving 10 g of psyllium respectively. Although additive effect was observed in the group receiving combination compared with group receiving lovastatin, the observed difference was not statistically significant. No significant changes from baseline in HDL-C levels occurred. CONCLUSIONS: Psyllium soluble fibre should be considered as a safe and well-tolerated dietary supplement option to enhance cholesterol lowering.

Emergency surgery in orbital trauma: a neurosurgical view.

This study is an analysis of five cases of orbital trauma causing proptosis, paralysis of extraocular muscles with or without associated visual failure. All the cases were treated by a Neurosurgical team. Either a frontal craniotomy or a lateral orbitotomy was performed. Plain X-rays of the skull and Computerised Tomography (C.T. Scanning) were the main investigations. Results were encouraging both functionally and cosmetically. Early diagnosis and an aggressive approach to orbital decompression can achieve good results.
