The Effects of Bitter Kola Supplemented Diet on Hepatotoxicity of Mercury in Wistar Rats
The effect of bitter kola on the hepatotoxicity following mercury
poisoning (mercuric chloride solution of 10ppm) was investigated in
rats for a duration of six weeks. Thirty (30) acclimatized Wistar rats
were divided into five groups(n=6).Group I served as control and were
fed on normal rat chow and clean water ad libitum, group II received
normal chow and mercury contaminated water (10ppm), group III animals
were given clean water and 5% w/w bitter kola supplemented rat chow,
group IV rats received bitter kola supplemented rat chow and mercury
contaminated water, group V animals were placed for the first week of
the experiment on mercury contaminated water and normal rat chow before
substituting with clean water and bitter kola supplemented rat chow.
Two (2) animals from each group were sacrificed at the end of 2nd, 4th
and 6th week and blood collected by cardiac puncture before the liver
was harvested .Serum Alkaline phosphatase (ALP), Glutamate Oxaloacetate
Transaminase (GOT), Glutamate Pyruvate Transaminase (GPT) and hepatic
content of Mercury (Hg) were determined by standard laboratory methods.
The results (Mean \ub1 SEM) showed that G kola supplemented diet
significantly lowered the hepatic mercury content as well as limited
the hepatotoxic effects of the heavy metal indirectly assessed by
measurement of the serum levels of alkaline phosphatase and the
transaminases. @ JASE

Understanding the neuroprotective effect of tranexamic acid: an exploratory analysis of the CRASH-3 randomised trial
Background: The CRASH-3 trial hypothesised that timely tranexamic acid (TXA) treatment might reduce deaths from intracranial bleeding after traumatic brain injury (TBI). To explore the mechanism of action of TXA in TBI, we examined the timing of its effect on death. Methods: The CRASH-3 trial randomised 9202 patients within 3 h of injury with a GCS score ≤ 12 or intracranial bleeding on CT scan and no significant extracranial bleeding to receive TXA or placebo. We conducted an exploratory analysis of the effects of TXA on all-cause mortality within 24 h of injury and within 28 days, excluding patients with a GCS score of 3 or bilateral unreactive pupils, stratified by severity and country income. We pool data from the CRASH-2 and CRASH-3 trials in a one-step fixed effects individual patient data meta-analysis. Results: There were 7637 patients for analysis after excluding patients with a GCS score of 3 or bilateral unreactive pupils. Of 1112 deaths, 23.3% were within 24 h of injury (early deaths). The risk of early death was reduced with TXA (112 (2.9%) TXA group vs 147 (3.9%) placebo group; risk ratio [RR] RR 0.74, 95% CI 0.58–0.94). There was no evidence of heterogeneity by severity (p = 0.64) or country income (p = 0.68). The risk of death beyond 24 h of injury was similar in the TXA and placebo groups (432 (11.5%) TXA group vs 421 (11.7%) placebo group; RR 0.98, 95% CI 0.69–1.12). The risk of death at 28 days was 14.0% in the TXA group versus 15.1% in the placebo group (544 vs 568 events; RR 0.93, 95% CI 0.83–1.03). When the CRASH-2 and CRASH-3 trial data were pooled, TXA reduced early death (RR 0.78, 95% CI 0.70–0.87) and death within 28 days (RR 0.88, 95% CI 0.82–0.94). Conclusions: Tranexamic acid reduces early deaths in non-moribund TBI patients regardless of TBI severity or country income. The effect of tranexamic acid in patients with isolated TBI is similar to that in polytrauma. Treatment is safe and even severely injured patients appear to benefit when treated soon after injury.
