Background: fertility rates using horse frozen-thawed semen remain lower than in other livestock species. This fact further suggests that horse semen hold intrinsic sensitivity to cryoinjury that must be investigated. Moreover, there is a substantial influence of genetic factors and diluent choice upon horse cryopreservation outcome. Collectively, these genetic and technical properties of horse semen could be explored to identify factors or conditions that may increase semen viability after freeze-thawing. The aim of this work was to evaluate the effect of diluents Botu-Crio®,Lactose-EDTA®, and INRA-82® on cryopreserved semen from stallions with high (HFA) and low freezability (LFA).Materials, Methods & Results: frozen-thawed semen was evaluated for motility, membrane integrity, and sperm DNA fragmentation using the thermoresistance test (TRT). Comparisons for each parameter were done in a pair-wise fashion between HFA and LFA semen at one-hour intervals during the TRT (0 h - 4 h). Sperm motility in HFA, regardless of the diluent, was larger (P < 0.05) than LFA, both on 0h and 1h. In the 2h evaluation, sperm motility using Botu-Crio® and Lactose-EDTA® was greater (P < 0.05) for HFA. Analysis of sperm membrane integrity was similar between HFA and LFA semen (P > 0.05) at 0 h and 3 h. Sperm DNA fragmentation was lower (P < 0.05) in HFA semen at 0 h and 1 h. Discussion: frozen-thawed semen from stallions of high freezing ability showed greater motility at all analysis, irrespectively of diluent choice, suggesting a strong influence of genetic factors on cryopreservation outcome. Membrane integrity was similar immediately after thawing but did differ later on other TRT time-points, irrespectively of diluent choice. As observed for motility, it was expected that sperm cells of stallions of HFA would show higher membrane integrity than their LFA counterparts. Sperm DNA fragmentation was quite low for both groups, as described in horses. Surprisingly, sperm DNA fragmentation incidence was constant throughout the analysis for both HFA and LFA. It was initially envisioned that increased DNA fragmentation would be found in semen from LFA stallions, since it is caused by multiple origins such as genetic factors. In conclusion, the semen diluent affects horse sperm motility after thawing, particularly from stallions with lower semen freezability.

Quality Assessments

Boar semen is voluminous and ejaculated as jets or fractions of pre-sperm, sperm rich (SRF) and post-sperm rich fractions. Recent studies have reported more resilient characteristics of sperm in initial portions of SRF towards cold shock and cryopreservation. The present study was conducted to assess the quality of specific fractions of SRF, namely, first 10mL of SRF (F1) and rest of SRF (F2) in Large white Yorkshire (LWY) boar semen. Ejaculates were collected using gloved-hand technique and were subjected to quality assessments of volume, pH, sperm progressive motility, concentration, plasma membrane integrity, abnormality, acrosome integrity and sperm membrane cholesterol. Upon statistical analysis, significant differences were noticed in volume, pH, sperm concentration and sperm membrane cholesterol between fractions of the ejaculate.

Cannabis sativa L. is a medicinally important weed of family Cannabaceae generally grows along road-sides and waste-lends in Punjab, Pakistan. In the present study, antifungal effect of leaf extract of this weed was assessed against Aspergillus flavipes. Methanolic leaf extract of the weed was partitioned into five fractions using organic solvents of variable polarities. A range of concentrations (1.562 to 200 mg mL-1) of each fraction was used in laboratory bioassays. n-Butanol fraction showed the highest antifungal activity followed by chloroform and n-hexane fractions causing 68–82%, 52–82% and 42–82% decrease in biomass of A. flavipes. Ethyl acetate showed a moderate antifungal potential while aqueous fraction showed the least antifungal activity causing 47–76% and 38–73% reduction in fungal biomass, respectively. This study concludes that n-butanol fraction of leaf extract of C. sativa is highly effective in controlling growth of A. flavipes.

Abstract Objectives Ocimum gratissimum L. is used in traditional medicine for the treatment of bacterial infections and anaemia. This study was designed to evaluate the effect of O. gratissimum leaf extract on phenylhydrazine (PHZ)-induced anaemia and toxicity in rats. Methods The experimental rats were divided into five groups (A–E) (n=6/sex/group). Each rat in groups B–E was intraperitoneally administered 50 mg/kg of PHZ for two consecutive days. Group A (normal control) did not receive any PHZ, group B (negative control), group C received orally 5 mg/kg ferrous sulphate whereas groups D and E received 200 and 400 mg/kg O. gratissimum leaf extract respectively, for 14 days. Results Red blood cell count, packed cell volume, haemoglobin concentration and high-density lipoprotein increased significantly (p<0.05) whereas low-density lipoprotein and very-low-density lipoprotein decreased in extract-treated groups when compared to the negative control. O. gratissimum (400 mg/kg extract) and standard drug (5 mg/kg ferrous sulphate) significantly (p<0.05) reduced the levels of aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase. Conclusions The results of this study indicate that O. gratissimum leaf extract has a restorative effect on the phenylhydrazine-induced metabolic distortions in the blood, liver, and kidney, and therefore could be used therapeutically as an anti-anaemic tonic.
