Objective: To investigate the effect of chromium picolinate on egg production, egg quality, serum biochemical indices and immune response. Methods: A total of 120 49 w old Beijing Red commercial layers were randomly allotted to one of five treatments, and fed a basal corn soybean meal diet and the basal diet supplemented with 0.4,2.0,10.0 or 20.0 mg/kg Cr as chromium picolinate under heat stress for 30 days.Results: Cr increased average egg weight(P0.20) on egg yield, feed intake and feed/egg ratio. Added Cr at 0.4 ,2.0,10.0 mg/kg enhanced (P

ObjectiveTo observe the influence of Danshen injection on the serum levels of TNF-α,IL-6 in patients with acute pancreatitis(AP).Methods70 patients with AP were randomly divided into the experimental and control group.The two groups were given conventional anti-inflammatory,antisecretory,antispasmodic,inhibition of pancreatic secretion treatment,and the experimental group were treated with Danshen injection.Before trealment and 1,2,4,6 days after treatment,the serum TNF-α,IL-6 levels were measured in both groups.The time of blood and urine amylase(AMS) returned to normal was observed in both groups.Results2,4,6d after treatment,the serum TNF-α,IL-6 of the observation group were lower than that of the control group( all P ＜ 0.05 ) ;The blood AMS recovery time of the observation group was ( 2.55 ± 0.71 ) d,which had no significant difference with that of the control group(2.46 +0.82)d(t =0.32,P ＞0.05 ),while urinary AMS recovery time of the observation group was (4.30 ±0.72 ) d,which was shorter than that of the control group ( 6.84 ± 0.88 ) d ( t =0.02,P ＜ 0.05 ).ConclusionDanshen injection could reduce the serum TNF-α,IL-6 levels in patients with AP,and had no effect on the serum amylase,with the trend of faster lower urinary amylase.
