OBJECTIVETo observe the effect of Polygonatum sibiricum on Yin deficiency model rats induced by long-term overload swimming.

METHODExcept for the normal group, all of the remaining rats performed the long-term overload swimming for eight weeks, with five days every week and once every day, to establish the Yin deficiency model. The daily swimming time increased from 10 min to 180 min at the end of the 7th week, with the water depth of 60 cm and the water temperature at 30 degrees C. After the success of the modeling, the rats were orally administered with different doses of aqueous extracts from P. sibiricum (2.5, 10 g x kg(-1)) for eight weeks. After the final administration, their blood were collected from orbits to measure immunoglobulin A, G and M (IgA, IgG, IgM), interleukin 2 and 6 (IL-2, IL-6) and cAMP, cGMP contents in plasma General behavioral indicators (weight, facial temperature, pain threshold and holding power) of rats were observed during the drug administration.

RESULTCompared with the model control group, aqueous extracts from P. sibiricum was given for eight weeks to significantly increase the rat weight and holding power of Yin deficiency model rats, decrease the facial temperature and the sensitivity of pain threshold, and increase IgA, IgG, IgM and IL-6 content and IgG content in serum, but without statistical difference. Aqueous extracts from P. sibiricum (10 g x kg(-1)) could also increase IL-2 content in serum, and decrease cAMP content and cAMP/cGMP ratio.

CONCLUSIONP. sibiricum could improve the general behavioral indicators (weight, holding power, pain threshold and facial temperature), immunologic functions (IgA, IgG, IgM) and cyclic nucleotide (cAMP, cAMP/cGMP), so as to ameliorate such Yin deficiency symptoms as dysphoria in chestpalms-soles, weight loss, soreness and weakness of waist and knees, immunologic dysfunction and cyclic nucleotide system disorders.

HPLC-ELSD was applied to explore the absorption mechanism of pulchinenosides (B3, BD, B7, B10, B11) in rats. The experimental results showed that the absorption rate constant, Ka value (B3, BD) and Permeability coefficient, Peff value (B3, B7) displayed significant difference (P <0.05) in various intestinal segments, The Ka value and Peff value of PRS was different from each other with the highest absorption in duodenum (duodenum > jejunum > colon > ileum); The PRS displayed excessive satuation as the concentration increased over 0.05-2.5 g · L(-1). There were no obvious linear correlations between Peff values and concentrations in duodenum (0.6007 ≤ R2 ≤ 0.7727); Ka and Peff value declined when the PRS was perfused with P-glycoprotein promoter digoxin, on the other hand, inclined when perfused with P-glycoprotein inhibitor verapamil with significant difference among PRS B3, BD, B7, B11 (P <0.05). All the above results demonstrated that B3, BD, B7 were greatly influenced by absorption sites, duodenum was the main absorption site; PRS didn't entirely transported in a concentration dependent manner, and the transporter-protein involved the transportation, so the intestinal absorption of the five pulchinenosides was not entirely passive diffusion; and PRS might be the substrates of P-glycoprotein.

OBJECTIVETo study the effects of long-term exposure to carbon disulfide (SC(2)) on cardiovascular system of workers.

METHODSThe concentrations of CS(2) were detected in the representative workshops with different exposure levels. The indicators related to cardiovascular system were tested in 633 workers occupationally exposed to CS(2), which included blood pressure, electrocardiogram, blood routine (blood RT), cholesterol (TCHO), triglyceride (TG) and so on. The data were analyzed by chi-square test and multiple logistic regression analysis.

RESULTSThe exposure concentration of CS(2) for 389 workers was less than or equal to 5 mg/m(3), which for other 244 workers was higher than 5 mg/m(3). The maximum exposure concentration of CS(2) was 15.73 mg/m(3). There were no significant effects of CS(2) on the electrocardiogram, red blood cells, white blood cells, blood platelet, TCHO and TG of workers. However, the positive effects of CS(2) on blood pressure and negative effects of CS(2) on hemoglobin were found. The rates of high TCHO, TG and hypertension in male workers were significantly higher than those in female workers (P < 0.05). The rates of high TCHO, hypertension and sinus arrhythmia in older workers (≤ 30 years old) were significantly higher than those in young workers (> 30 years old) (P < 0.05). The rate of sinus arrhythmia in workers with 1 - 10 working years was significantly higher than that in workers with more than 10 working years (P < 0.05). The rate of hypertension in workers with 1 - 10 working years was significantly lower than that in workers with more than 10 working years (P < 0.05).

CONCLUSIONThere were no significant effects of CS(2) exposure on the indexes of cardiovascular system of workers.
