Study on the Anti-inflammatory, Antitussive and Analgesic Effects of Jinhua Qingre Capsules / 医药导报

Objective To study the anti-inflammatory,antitussive,and analgesia effects of Jinhua qingre capsules.Methods The anti-inflammatory effect was assessed by the methods include xylene-induced mouse auricular swelling and histamine-induced pigment oozing from skin vessel in rats;The antitussive and analgesic effect were assessed by ammonia water induced cough model and acetic acid-induced twisting method.Results In anti-inflammation experiment,the high dose (12 g·kg-1) and moderate (6 g·kg-1) groups of Jinhua qingre capsules showed significant inhibitory effect on auricular swelling and significant difference compared with control group (P ＜ 0.01,P ＜ 0.05.);the high dose (10 g· kg-1) and moderate dose (5 g·kg-1) groups of Jinhua Qingre capsules play a marked inhibitory role in the increase in mouse peritoneal capillary permeability (P ＜ 0.01,P ＜ 0.05).In antitussive experiment,high dose (12 g· kg-1) and moderate dose (6 g· kg-1) groups had significant inhibitory effect on cough caused by ammonia water (P ＜ 0.01,P ＜ 0.05) compared with control group.In analgesic experiment,the high dose (12 g·kg-1),moderate dose (6 g·kg-1),and low dose (3 g·kg-1) groups effectively reduced the writhing frequency of mice (P ＜ 0.01,P ＜ 0.05).Conclusion Jinhua qingre capsules have potential effects on anti-inflammatory,antitussive,and analgesic.

Antiendotoxin effect of Jinhuaqingre capsules / 浙江大学学报·医学版

To investigate the anti-pyretic and anti-endotoxin effect of Chinese herb medicine Jinhuaqingre capsules.Thirty healthy male New Zealand rabbits with lipopolysaccharide-induced fever were divided into 5 groups (6 rabbits in each): animals in model group were given normal saline by gavage, animals in positive control group were given aspirin (0.2 g/kg), and animals in Jinhuaqingre groups were given Jinhuaqingre capsules 6.0, 3.0 or 1.5 g/kg, respectively. The changes in body temperature of rabbits were observed. Fifty healthy Kunming mice were divided into 5 groups (10 mice in each): mice in model group were given normal saline by gavage, mice in positive control group were given aspirin (0.2 g/kg), and those in Jinhuaqingre groups were given Jinhuaqingre capsules 6.0, 3.0, 1.5 g/kg, respectively. Matrix coloration method was used to detect the degradation rate of endotoxin in mice.The body temperature in rabbits of high and medium dose Jinhuaqingre capsule groups declined significantly 60 min after drug administration, and the temperature of high-dose group returned to the baseline after 300 min; while the body temperature of low-dose group started to decline at 180 min after drug administration. The endotoxin degradation rates in mice of high, medium and low dose groups was (56.73±3.12)%, (47.23±1.77)% and (21.08±2.30)% at 30 min after drug administration; those were (82.76±1.00)%, (64.75±1.77)% and (38.21±1.57)% at 60 min after drug administration, respectively.Chinese herb medicine Jinhuanigre capsules have anti-pyretic and anti-endotoxin effects, which may provide a new option for the treatment of heat-toxin syndrome.

The Inhibition on the Proliferation of Colorectal Carcinoma Cell Strain with Different Proliferative Potential by All Trans Retinoic Acid / 中国肿瘤生物治疗杂志

Objective: The inhibition on the proliferation of colorectal carcinoma cell strain with different proliferative potential by ATRA was investigated in present study, which would benefit for the therapy of ATRA on colorectal carcinoma. Methods: The proliferation of LS174T and CW-2 colorectal carcinoma cell strain inhibited by ATRA was determined using cell observation, FACS and MTT methods. Results: The growth speed of LS174T cell strain was faster than that of CW-2. ATRA played a significant role on inhibiting the proliferation of LS174T and CW-2 cell strain and inducting the cell differetiation in vitro. Conclusions: ATRA could inhibit the growth of LS174T and CW-2 cell strain. ATRA could inhibit the proliferation of colorectal carcinoma cell and induce cell differentiation to some extent, which was correlated with the concentration of ATRA.
