Comparison of the therapeutic efficacy of double-modality therapy, phonophoresis and cryotherapy in the management of musculoskeletal injuries in adult Nigerian subjects.

This study was designed to compare the efficacy of double-modality therapy, phonophoresis and cryotherapy in the management of pain among subjects who suffered from musculoskeletal injuries (MSIs).Sixty (60) subjects were assigned randomly to one of three groups: DMT group (n=20) received cryotherapy and 15% methyl salicylate phonophoresis, PHONO group (n=20) received 15% methyl salicylate phonophoresis and CRYO group (n=20) received cryotherapy and "sham? phonophoresis. Ultrasound at an intensity of 1.5 W/cm² and frequency of 1MHz was used to apply methyl salicylate while intermittent cryotherapy was the mode of application. Subjects? pre- and post-treatment pain perception scores (PPS) using visual analogue scale (VAS) were assessed and the sessions of treatment in all groups were recorded. Treatment was administered on alternate days and discharges were made in all groups when subjects were pain free. A total of 275 treatment sessions was recorded - 72 (26.2%) in DMT, 105 (38.2%) in PHONO and 98 (35.6%) in CRYO group respectively which indicated no significant difference (P>0.05). Nineteen (19), thirteen (13) and twelve (12) subjects were pain free in DMT, CRYO or PHONO groups respectively after 1 to 5 treatments. The difference in the severity of pain was significant (P<0.05) in each group post-treatment which suggests that DMT, phonophoresis and cryotherapy were equally effective. The study has demonstrated therapeutic efficacy of DMT, but it was not superior to the single treatment protocol of phonophoresis or cryotherapy. However, it might take fewer sessions in the DMT group to treat and make more than 90% of the subjects pain free and fit to return to active performance.

Evaluation of the efficacy of separate oral supplements compared with the combined oral supplements of vitamins C and E on sperm motility in Wistar rats.

Infertility is a major reproductive and social problem with a worldwide prevalence of 10-15%. While 11.8-39.0% of infertility cases are attributable to the female, 15.8-42.4% is attributed to the male and 8.0-11.1% to unknown factors. The study investigated the efficacy of the single versus combined regimes of antioxidant vitamins C and E oral supplements on sperm motility in the reproductively matured Wistar rats. Twenty [20] male Wistar rats aged 12 weeks and weighing between 182 g and 252 g were randomly grouped into 4 experimental blocks [A-D] of 5 rats each. Block A rats were served combined daily dose of 90 mg vitamin C and 15 mg vitamin E, block B rats had no treatment and served as control, block C rats were served daily dose of 15 mg vitamin E only while block D rats were served daily dose of 90 mg vitamin C only; all treatments were administered for 28 days. On the 29th day, the rats were humanely sacrificed and semen analyzed for sperm motility. The study showed that treatment with vitamins C and E as single regime significantly improved [P<0.01] the forward, progressive [category a] mean percentage sperm motility by 70 and 75 folds respectively while significantly decreasing [P<0.01] the non-progressive [category c] mean percent sperm motility by 8 and 5 folds respectively compared to the control mean percent sperm motility. We therefore conclude that sperm motility in the Wistar rats is significantly improved with the separate oral supplements of vitamins C and E as compared with the combined supplements.

A preliminary report on the Anti-Diarrhoeal benefit of Seleru: A possible adjunct HIV/AIDS Therapy

"Infection with the human immunodeficiency Virus (HIV) is assuming greater proportion. The global estimates of new infections keep rising. The cure for HIV infection/acquired immunodeficiency syndrome is related to the socio-economic status of the population. In our environment; poverty is a major undoing in the medical management of HIV/AIDS using orthodox antiretroviral drugs. Consequently; great attention is being turn to the exploration of herbal remedies in the management of this dreaded disorder. A concoction ""Seleru"" (Amodmat r) is claimed to have benefits for HIV/AIDS. We investigated the role of this concoction on diarrhoea; a distressing symptom of the syndrome. The antidiarrhoeal property of ""Seleru"" (Amodmat r) was investigated using the charcoal meal preparation; on albino wistar rat. The extract was administered at a dose range of between 100mg/kg to 800mg/kg body weight. Results show an antimotility effect on the gastrointestinal tract; supporting a usefulness of the extract in diarrhoeal states."

Time course of perfusion-induced myocardial edema resolution in rats.

Previous studies have demonstrated that crystalloid coronary perfusion can cause myocardial edema, but the time required for resolution of this edema has not been defined. Accordingly, studies were conducted in 30 rats. Myocardial edema was induced by coronary perfusion with 20 cc/kg of Plegisol (294 mOsm/liter) during aortic occlusion, which produced diastolic arrest. This was followed by whole blood reperfusion, which restored normal contractile function. Duration of reperfusion in minutes was zero (group 0, n = 6), one (group 1, n = 6), five (group 5, n = 6), or fifteen (group 15, n = 6). A control group (n = 6) was studied without edema or reperfusion. Data included heart weight and myocardial water content. Left ventricular pressure-volume curves were measured in groups 1, 5, and 15. Myocardial water content increased significantly from 75.7 +/- 0.5% (SD) in the control group to 79.7 +/- 1.1% (P < 0.05) in group 0 and then decreased significantly to 77.3 +/- 0.7, 75.2 +/- 1.4, and 75.3 +/- 1.6% in groups 1, 5, and 15, respectively. Water content in group 1 was also significantly greater than in groups 5 and 15. Heart weight changes were not statistically significant. Normalized pressure-volume relationships shifted rightward with increasing reperfusion time, but changes were not statistically significant. We conclude that edema induced by crystalloid coronary perfusion of the arrested heart resolves in the beating heart after less than 5 min of blood reperfusion.
