Tiliacora racemosa Colebr. belonging to the family Menispermaceae, is the biggest storehouse of diphenyl bisbenzylisoquinoline (DBBI) alkaloids. Exhaustive chemical processing of the root of T. racemosa by the application of modern separation techniques yielded a DBBI alkaloid which was identified as tiliacorine using sophisticated spectroscopic methods (UV, IR, $^1H-NMR$, MS). Haematological study with tiliacorine proved that there was no abnormal haematological results in comparison with the normal values. Chronic toxicity study with tiliacorine revealed that the alkaloid is devoid of any hepatotoxic and nephrotoxic action.

Background: Lung cancer is one of the most common types of cancer causing high morbidity and mortality worldwide. An increasing incidence of lung cancer has been observed in India. Objectives:To evaluate the clinicpathological profile and haematological abnormalities associated with lung cancer in Bangalore, India. Materials and Methods: This prospective study was carried out over a period of 2 years. A total of 96 newly diagnosed and histopathologically confirmed cases of lung cancer were included in the study. Results: Our lung cancer cases had a male to female ratio of 3:1. Distribution of age varied from 40 to 90 years, with a major contribution in the age group between 61 and 80 years (55.2%). Smoking was the commonest risk factor found in 69.7% of patients. The most frequent symptom was cough (86.4%) followed by loss of weight and appetite (65.6%) and dyspnea (64.5%). The most common radiological presentation was a mass lesion (55%). The most common histopathological type was squamous cell carcinoma (47.9%), followed by adenocarcinoma (28.1%) and small cell carcinoma (12.5%). Distant metastasis at presentation was seen in 53.1% patients. Among the haematological abnormalities, anaemia was seen in 61.4% of patients, leucocytosis in 36.4%, thrombocytosis in 14.5% and eosinophilia in 19.7% of patients. Haematological abnormalities were more commonly seen in non small cell lung cancer. Conclusions: Squamous cell carcinoma was found to be the most common histopathological type and smoking still remains the major risk factor for lung cancer. Haematological abnormalities are frequently observed in lung cancer patients, anaemia being the commonest of all.

This study was conducted to investigate the effect of bisphenol A (BPA; 4,4' -isopropylidenediphenol) on haematological parameters of Korean rockfish, Sebastes schlegeli in laboratory condition, Fish were randomly distributed into three treatment groups which were received of 0.1, 1 and 10 mg BPA $kg^{-1}$ body weight. They were injected four times intraperitoneally at days 0,3,7 and 12 with BPA. Control group was subjected to the same regime using an equal volume of 60% ethanol-mixed PBS carrier injection only. Fish from each group were sacrificed on day 15 after first injection for haematological assay. Observations on haematological parameters indicated BPA-treatment induced lower level of red blood cell counts and hemoglobin concentration. Serum chloride, calcium, glucose, bilirubin and blood urea nitrogen concentrations increased following exposure to BPA at 10 mg $kg^{-1}$ body weight. In contrast, serum cholesterol in fish exposed to BPA decreased. Serum transaminase and lactate dehydrogenase activities after the highest level of 10 mg $kg^{-1}$ PBA was significantly increased. These results demonstrate that BPA have induced adverse impact on haematological parameters in the Korean rockfish, Sebastes schlegeli.

Our study investigated the effects of Solanum macrocarpon (African eggplant) on haematological and biochemical parameters of male albino rats exposed to urban air pollution ($O_3$, $PM_{10}$, CO, $SO_2$, $NO_2$ and VOC). Male albino Wistar rats were exposed for 63 days either to urban air pollution without treatment (A); oral supplementation with Solanum macrocarpon given at 36 and 75 mg/kg body weight (BW), representing C and D respectively and exposed to air pollution; oral supplementation with Solanum macrocarpon given at 75 mg/kg BW after exposure to air pollution (B); or kept in animal house without exposure to air pollution (E). Animals exposed to air pollution showed significant alterations in haematological and biochemical parameters signaling that the blood and organs were badly injured. There were significant elevations in white blood cells (WBC) and its indices, reduction in red blood cells (RBC) and significant depletions of non-enzymic antioxidants, total protein and increase in lipid peroxidation values. Solanum macrocarpon supplementation in the feed of animals halted significantly the deleterious effects of air pollution, with co-administration during exposure given better results.

Chimeric antigen receptor (CAR) T cells, which express a synthetic receptor engineered to target specific antigens, have demonstrated remarkable potential to treat haematological malignancies. However, their transition beyond haematological malignancy has so far been unsatisfactory. Here, we discuss recent challenges and improvements for CAR T cell therapy against solid tumors: Antigen heterogeneity which provides an effective escape mechanism against conventional mono-antigen-specific CAR T cells; and the immunosuppressive tumor microenvironment which provides physical and molecular barriers that respectively prevent T cell infiltration and drive T cell dysfunction and hypoproliferation. Further, we discuss the application of CAR T cells in infectious disease and autoimmunity.

The effect of an ethanolic extract of the plant Trianthema portulacastrum L. on the $CCI_4$-induced chronic hepatocellular damage of Swiss albino mice has been investigated. The normal mice received olive oil (0.2 ml/mouse) for five weeks. The $CCI_4$ control mice, on the other hand, received $CCI_4$ (0.05 ml/mouse) in olive oil for five weeks. The extract was administered at the dose of 100 mg/kg or 150 mg/kg for five weeks by gastric intubation in addition to $CCI_4$ treatment. The $CCI_4$ administraction alone caused hepatocellular necrosis, severe anemia, leucopaenia, lymphocytopaenia, neutrophilia, eosinophilia and haemoglobinaemia along with the alterations of plasma albumin and globulin. The administration of plant extract (at 100 or 150 mg/kg) restored the $CCI_4$-induced alterations of the haematological parameters to the normal level. The extract of T. portulacastrum elicited a marked protection against $CCI_4$-induced hepatotoxicity as indicated by the several haematological parameters, related indices of formed elements, and different fractions of plasma protein. We also observed the dose-dependent antihepatotoxic effect of the extraction on these mice. The 150 mg/kg of extract was found to be more effective in normalizing the toxic effects of $CCI_4$ on the above parameters of mice. These results suggest that the hepatoprotective effect of T. poltulacastrum could be caused by its critical involvement in modulating several factors associated with erythropoiesis, and the boosting of general immunity of the host.

Di-2-ethylhexyl phthalate (DEHP) is a widely used plasticizer known to be a suspected xenoestrogen and a causative agent of oxidative damage to the RBC cell membrane ir vitro. We evaluated the toxic effects of a scarcely documented aquatic environmental pollutant, DEHP, on selected haematological endpoints in the bagrid catfish, Pseudobagrus fulvidraco. Bagrid catfish were exposed to DEHP (300, 1,000 mg DEHP kg body weight$^{-1}$) through thrice intraperitoneal injection and effects were assessed in blood of the exposed organisms. Haematological property, serum organic and inorganic chemistry were monitored in blood of Bagrid catfish. DEHP exposed-fish showed erythropenia; low hematocrit (Ht) and hemoglobin (Hb) content and red blood cell count showed a significantly higher than in that of the control group. The treatment group showed a significantly lower concentration of serum total protein, cholesterol and triglyceride compared with those in the control group. The value of calcium and osmolality were significantly decreased in the DEHP treatment group, compared with the control group.

Effects of oral administration with fermented product from sewage in land-based seawater fish farm on haematological disturbance in the olive flounder, Paralichthys olivaceus was investigated. After 4 weeks of conditioning with a basal diet, fish were divided into 4 groups and provided experimental diet (0.1, 0.5, 1.0 and 2.0%) supplement of fermented sewage for 80 days. Proximal analysis was performed for the product of sewage which was fermented by lactic acid and yeast. RBC count, hemoglobin concentration and hematocrit value were increased according to the treated periods, however, no statistical difference was observed between control and treatment groups. There were no significant difference in serum organic, inorganic compounds and enzyme activities between control and treatment groups. This study hypothesized that the supplement of fermented product from sewage in land-based seawater fish farm might be an additive supplement for source of fish diet in view of haematological examination. Recycling of the sewage may be an economic artificial sources of diet for fish aquaculture practices.

An experiment was conducted on eight bullocks of Hariana cattle study draft efficiency using different appliances, changes in their physiological, biochemical and haematological parameters, and how the body tries to maintain these within normal physiological range. Blood collection was done at pre-exercise, three hours after exercise and two hours post exercise in summer and winter seasons of the year 1990-91. Average pulse rate and respiration rate per minute were found to be $63.09{\pm}0.78,\;25.60{\pm}0.54,\;97.21{\pm}2.51,\;63.37{\pm}2.70,\;64.05{\pm}1.90,\;25.33{\pm}1.20$, respectively, at pre-exercise, three hours exercise and two hours post exercise rest. The seasonal differences were found to significant and the values were higher in summer than in winter. After two hours post exercise rest Hariana bullocks regained their normal values for all the parameters, except that pulse rate, respiration rate and serum sodium during summer did not reach the pre - exercise levels.
