Objective To explore the efficacy of HAART for AIDS combined of oral fungal infection. Methods 60 AIDS patients combined with fungal infection were selected and divided into therapy group (n =30) and control group (n = 30) by HAART criteria. Individuals in control group were treated with routine care, including washing mouth by 2％ sodium bicarbonate, Smearing glycerol reducing mold on local skin, and taking fluconazole or itraconazole capsules 100 mg orally, and all above were taken twice a day, meanwhile nutrition therapy and oral nursing were strengthened. Therapy group were treated with HAART on the base of routine care. Results Effect rate between the two groups was significantly different (X2 = 6. 667, P ＜ 0. 05). Cure rate and recurrence rate were also different (X2 = 4. 286,4. 356; P ＜ 0. 05). Conclusions Application of HAART on the basis of routine care for AIDS combined of oral fungal infections has better efficacy and lower recurrence rate and improve the clinical symptom and raise the life quality of the patients.

OBJECTIVETo observe and compare the protective effect of garlic oil against carbon tetrachloride (CCL)-induced acute liver injury.

METHODSThe experiments include 4 preventive groups and 2 therapeutic groups. In every preventive and therapeutic group, the mice were randomized into 6 groups with 15 each, including one negative control group, one solvent control group, one CCl4 model group and 3 garlic oil groups (25, 50, and 100 mg/kg body weight). Before given a single gavage of CCl4 (80 mg/kg), the mice were pretreated with garlic oil by gavage in preventive group 1 (30 days, once daily), preventive group 2 (5 days, once daily), preventive group 3 (ahead of 2 h, once), preventive group 4 (immediately, once) or the vehicle (corn oil, 10 ml/kg) in solvent control group. In therapeutic groups, the mice were gavaged garlic oil 2 h (once, in therapeutic 1) or for 5 days (once daily, in therapeutic 2) after administration CCl. After 24 h of the last administration, blood was collected and centrifuged at 2500 r/min at 4 degrees C for 10 min, and serum was removed to measure ALT and AST activities. The liver was dissected, weighed to calculate the liver coefficient (relative liver weight). At the same time, the liver samples were studied by histological examinations.

RESULTSCompared with negative group, the liver coefficient and the activities of ALT and AST in serum of model group were increased remarkably (P < 0.01). Compared with CCl model group, the liver coefficient and the activities of ALT and AST in serum were decreased significantly (P < 0.01) by garlic oil dose-dependently in each preventive group. Simultaneously, histological assessment showed that garlic oil effectively alleviated hepatocyte injuries induced by CCl4. Comparing the preventive effects of garlic oil in every group, it was better in preventive group 3 than others. However, all indexes and histological examinations in therapeutic group 1 did not show the difference with those of CCl4 model group. In therapeutic group 2, all indexes recovered after 5 d of CCl4 administration.

CONCLUSIONSGarlic oil can prevent acute liver injury induced by CCl4 and the effect is better in ahead of 2 h group than others.

OBJECTIVETo investigate whether the alterations of microtubule and microfilament expression are responsible for the neurotoxicity of carbon disulfide.

METHODSWistar rats were administered with carbon disulfide by gavage at a dosage of 300 or 500 mg/kg for continuous 12 weeks (five times per week). Spinal cords of carbon disulfide-intoxicated rats and their age-matched controls were Triton-extracted and ultracentrifuged to yield a pellet and a corresponding supernatant fraction. Then, the contents of alpha-tubulin, beta-tubulin, and beta-actin in both fractions were determined by immunoblotting. In the meantime, their mRNA levels in spinal cords were quantified using reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTSIn the supernatant fraction, the contents of beta-tubulin and beta-actin in both treated groups increased significantly (P < 0.01) the content of beta-tubulin increased by 141% and 158% respectively, and the content of beta-actin increased by 19% and 32% respectively. In the pellet fraction, the content of beta-tubulin in both groups increased by 107%(P < 0.01) and 118%(P < 0.01) respectively, and the others keep unaffected. In the meantime, the levels of of mRNA expression of beta-tubulin and beta-actin gene were elevated consistently in CS(2)-treated groups (P < 0.01) the levels of mRNA expression of beta-tubulin increased by 207% and 212% respectively, and the levels of mRNA expression of beta-actin increased by 94% and 91% respectively.

CONCLUSIONCarbon disulfide intoxication results in alternations of microtubule and microfilament expression, and the alternations might be related to its neurotoxicity.

Ginseng is a traditional Chinese medicine which has been used in treating anemia for thousands of years. It is composed of a lot of components. The main component is total saponin of panax ginseng (TSPG), which contains more than 20 ginsenosides including Rg1, Rb1 and so on. Previous studies have reported that total saponin of panax ginseng could promote hematopoiesis by stimulating proliferation of human erythroid grogenitor cells CFU-E and BFU-E, however, it had different effects on CFU-GM reported by various laboratories. In this study, CFU-GM assay was adopted to observe the ginsenosides Rg1 and Rb1's effects on the proliferation of human marrow grannulocyte-macrophage progenitor cells. The results showed that Rg1 and Rb1 had obvious promotive effect on the proliferation of CFU-GM, and the increasing rates of colony formation were up to (70.6 +/- 6.8)% and (65.1 +/- 6.3)%, respectively. There was no inhibiting effect on CFU-GM in high concentrations of Rg1 and Rb1. It is suggested that Rg1 and Rb1 can stimulate the proliferation of human granulocyte-macrophage progentors. The results of TSPG's various effects on CFU-GM might be caused by different contents of ginsenosides in TSPG used in different laboratories.

Objective To assess the safety, immunogenicity and efficacy of group A and C meningococcal polysaccharide vaccine (A/C MPV) in response to an outbreak of group C meningococcal disease. Methods A vaccination campaign with A/C MPV was prompted 6 weeks after the use of group A MPV in Laibin city, Guangxi, where an outbreak of group C meningococcal meningitis occurred in 2002.Vaccinees were observed for local and systemic reactions after the vaccination and followed up for the meningococcal disease for 5 years. Blood samples were collected from 71 people in the epidemic and 43 in the non-epidemic areas before and 1 month after the vaccination and examined by ELISA to detect IgG antibodies to group A and C polysaccharides. Results The vaccination coverage was 97%. No significant adverse reactions were observed. The positive rates of group C antibodies after vaccination was between 97.67% and 100% among the populations in the epidemic and non-epidemic areas, as well as among those negative and positive for group C antibodies prior to the vaccination.The geometric mean anti-C concentrations ranged 30.81 μg/ml to 37.44 μg/ml, showing no significant difference between groups. The incidence rate of meningococcal disease in students with timely immunization (218.58/100 000) dropped by 69.02% , when compared to that in those with delayed immunization (705.72/100 000). No clinical cases were identified during the follow-up period of 15 760 person-years. Conclusion The vaccination campaign with the Chinese group A/C MPV seemed successful in controlling the group C meningococcal outbreak.The vaccine was shown to be safe even administered after the group A vaccine only 6 weeks apart. It could induce high levels of antibodies in vulnerable population and significantly increase antibody levels in seropositive individuals, thus providing a protection of at least 5 years.
