Effect of paper mill effluent on germination of green gram (Phaseolus aureus Roxb.) and growth behaviour of it's seedlings.

Effect of paper mill effluents on Phaseolus aureus Roxb was studied. The effluent significantly inhibited germination of root and shoot length. The bio-chemical injury does not appear spontaneously but with the increase in effluent treatment there is reduction in observed biochemical parameters (chlorophyll, protein, amino acid, nuclic acids and carbohydrate) which are negatively correlated. The shoots of the seedlings were found to be resistant; whereas roots of the seedlings were susceptible to paper mill effluent treatment.

Hypohaptoglobinaemia as a biochemical and epidemiological marker of falciparum malaria.

OBJECTIVES: The study was conducted in two parts to find out the usefulness of hypohaptoglobinemia (Hpo) as a biochemical and epidemiological marker of malaria. Part-I study was conducted in a Medical College Hospital to find out Hpo in malaria and the time required for normalization of Hpo. Part-II study was undertaken in two endemic areas of malaria to find out the prevalence of Hpo and haptoglobin index (HI) throughout the year along with other indicators of malaria. METHODS: In Part-I study, 172 patients of malaria constituting 58, 52 and 62 patients of cerebral malaria, uncomplicated falciparum malaria and vivax malaria, respectively were enrolled. Along with routine haematological and biochemical investigations, haptoglobin (Hp) estimation was done by endoplate haptoglobin test kit on admission and at 15 days interval for 3 months. In Part-II study Hp was estimated is 305 subjects in two endemic areas of malaria. HI, parasitic index, slide positivity rate (SPR), slide falciparum rate (SFR) were estimated throughout the year and HI was compared with these epidemiological markers. RESULTS: Hpo was present in 102 (92.7%) cases of falciparum malaria which was significantly more than vivax malaria and non-malarial fever. The normalisation of Hpo took about a month or more. The incidence of Hpo was 32.1% is endemic and 4.7% in nonendemic area of malaria. The HI varied between 12.4 to 25.2% throughout the year and was found to be a better marker than other classical markers of malaria. CONCLUSION: Hypohaptoglobinemia may be considered as a useful indirect indicator of falciparum malaria. HI can be used as an epidemiological maker which is better than classical markers of malaria used at present.

Mitoxantrone, mitomycin-C, methotrexate combination chemotherapy with radiotherapy and/or surgery in stage III (T4B, NO-2, M0) breast cancer.

Results of primary surgery with or without locoregional radiotherapy (LRRT) are poor in stage III (T4b, NO-2, M0) breast cancer. Combination of mitoxantrone, mitomycin-c and methotrexate (MMM) has been reported to be as efficacious as doxorubicin based protocols with advantages of reduced nausea, vomiting, alopecia and cardiotoxicity. We tested MMM chemotherapy with LRRT and surgery in locally advanced breast cancer (LABC) with a view to assess response, survival, breast conservation, cost and toxicity. Fifty two previously untreated patients were given Mitoxantrone: 8 mg/m sq by infusion on days 1 and 21, Mitomycin-C: 8 mg/m sq by infusion on day 1 and Methotrexate: 35 mg/m sq i.v. on days 1 and 21. Cycles were repeated every 42 days. After 3 cycles LRRT was given if lump reduced to less than 2 cms. Otherwise patients were subjected to modified radical mastectomy (MRM) or radical mastectomy (RM). Following this 3 more cycles of chemotherapy were given. Patients with soft tissue, skin or heavy nodal involvement also received LRRT. Tamoxifen 20 mg daily was prescribed at the end of chemotherapy to postmenopausal patients. Complete/partial responses were seen in 5 and 26 patients, respectively after chemotherapy giving an overall response of 59.5%. Twenty four patients each had LRRT and MRM/RM. Responses could be significantly enhanced by LRRT/and or surgery. Nineteen out of 25 relapses were at distant sites. Breast conservation was achieved in 24/52 (46%) patients. Three year disease free and overall survival was 54% and 65%, respectively. There was 1 toxic death. Severe prolonged myelosuppresion was seen in those who also received LRRT. Mucositis, alopecia, nausea and vomiting were minor problems. Overall, combination was less expensive than doxorubicin based protocols.
