RESUMO

The present study was undertaken to assess the effects of stem extract of Tinospora cordifolia (Giloy or Guduchi) in the semen extender on seminal parameters, leakage of intracellular enzymes and antioxidants in semen of Sahiwal bull. A total of 48 ejaculates from four bulls were selected for the study. Spermatozoa of 25 × 106 were incubated in 100, 300 and 500 µg of stem extract of Guduchi as Gr II, III and IV, respectively, and pre-freeze and post-thaw semen samples were analysed for seminal parameters [motility, viability, total sperm abnormality (TSA), plasma membrane integrity (PMI) and acrosomal integrity (AcI)], intracellular enzymes [aspartate aminotransferase (AST) and lactate dehydrogenase (LDH)] and seminal antioxidants [superoxide dismutase (SOD) and catalase] in comparison with an untreated control group (Gr I). The results revealed that stem extract-treated semen had significantly (p < .05) higher motility, viability, PMI, AcI, SOD and catalase and had significantly (p < .05) lower TSA, AST and LDH compared to those in untreated control group at pre-freeze and post-thaw stages. Semen treated with 100 µg stem extract/25 × 106 spermatozoa had significantly (p < .05) higher motility, viability, PMI, AcI, SOD and catalase and had significantly (p < .05) lower TSA, AST and LDH compared to those in control, 300- and 500-µg-treated groups at pre-freeze and post-thaw stages. Further, these seminal parameters and antioxidants were showing decreasing trend and TSA and leakage of intracellular enzymes were showing increasing trend from Gr II to Gr IV at pre-freeze and post-thaw stages. Thus, 100 µg/25 × 106 spermatozoa were optimum or suitable dose for cryopreservation of Sahiwal bull semen. The study concluded that T. cordifolia stem extract 100 µg/25 × 106 spermatozoa in the semen extender can be effectively utilized to reduce the oxidative stress and improve the pre-freeze and post-thaw seminal parameters in Sahiwal bull. However, further studies on effects of different concentrations of stem extract on in vitro or in vivo fertility trials are to be conducted to assess the impact of the stem extract supplementation in the semen extender on field pregnancy outcomes in bovine species.

RESUMO

Medicologal service is one of the vital component of hospital services which helps in providing justice to the victim and strengthen the public relations. Any shortcomings in the form of disrespect, negligence and inadvertant delay on the part of hospital staff towards the patient masks the image of the hospital. Some events such as expert evidence, methods of proff, assesment of disability, the work of the medical examiner, Blood groupings, organ transplantation and effectiveness of other tests have great practical importance in providing justice. Steps to deal with medicologal cases effectively and minimising legal complications are enumerated.
