RESUMEN
Aim: To determine the Red cell indices and Reticulocyte count values in HIV-positive patients under antiretroviral treatment and those not under antiretroviral treatments with varying durations of HIV infection and antiretroviral treatments. Study Design: Case-control study. Place and duration of Study: The study was carried out at Nnamdi Azikiwe University Teaching Hospital Nnewi, Nigeria from March to August 2013. Methodology: 181 subjects were recruited consisting; Sixty (30 males and 30 females) HIV subjects under antiretroviral therapy (ART) with an HIV infection and ART duration of <1–5 years, >5 –8 years and >8–17 years; Sixty (25 males and 35 females) HIV subjects not under ART (non-ART) with an infection duration of <1–3 years, >3–6 years and >6–11 years; and Sixty-one (31 male and 30 female) apparently healthy seronegative control subjects. The Reticulocytes count, Packed cell volume (PCV), Haemoglobin (HGB), Red blood cell count (RBC), Mean cell volume (MCV), Mean cell haemoglobin (MCH), Mean cell haemoglobin concentration (MCHC) and Human Immunodeficiency virus (HIV) status of the study subjects were determined. Results: MCV and MCH for ART and non-ART subjects were significantly increased compared with control group (P<.05) and the differences with varying durations of HIV infection and antiretroviral therapy were not significant (P>.05). Moreover, there was a significant decrease in the mean HGB, RBC, MCHC of ART and non-ART compared with control (F=8.51; 133.85; 33.32; P<.05 respectively) and their differences with varying durations of infection and antiretroviral therapy were not significant (P>.05). MCV were significantly higher in ART compared with non-ART (P<.05). Conclusion: There is no significant variation in Red cell indices and Reticulocyte count values in HIV patients with differences in duration of HIV infection and antiretroviral therapy.
RESUMEN
In order to determine the pharmacological effects of Crocus (traditionally classified as an herb helpful in eliminating Blood Stagnation), the 11-dehydro TXB<sub>2</sub>, platelet aggregation, blood viscosity and laboratory data of 12 healthy sexually mature females were examined during the menstrual, follicle and corpus luteum phases before the test substance was administered. Compared with the follicle or corpus luteum phases, higher levels of 11-dehydro TXB<sub>2</sub> and increased mean cell volume (MCV) were found during the menstrual phases. This suggested that the increase in blood viscosity may be due to a lowering of erythrocyte deformation resulting from increased mean cell volume. From the fact that the highest endometrial PGE<sub>2</sub> value was exhibited during the menstrual Phase, PGE<sub>2</sub> was thought to be involved in the MCV increase. Next, plain hot water was administered to the six cases in the control group (for four weeks), and Crocus infusion administered to the other six cases (for four weeks), after which a comparative study was made of their indicators. The significant lowering of the MCV and blood viscosity during the menstrual phase upon Crocus administration suggested that an improvement in erythrocyte deformation brought about by decreased MCV played a role in the reduction of blood viscosity. Moreover, a decrease in 11-dehydro TXB<sub>2</sub> was observed during the low blood estrogen follicle phase. It has been reported that there is an overall increase in blood viscosity and acceleration of platelet and thrombin synthesis associated with the disease state known as “Blood Stagnation”. From the clear effects of Crocus upon these indicators, its effectiveness as an herb useful in eliminating Blood Stagnation in healthy sexually mature females was indicated.
