ABSTRACT
Koradi Thermal Power Station requires 1-1.2 lakh m3 of water per day and pond No. 3 is the source of water supply of Koradi Thermal Power Station. This Pond No. 3 is being replenished by Pench Canal water, but water undergoes significant changes in quality after entering Pond No. 3 and hence this aspect may be crucial for raw water intake at Water Treatment Plant Stg-II of Koradi Thermal Power Station. Therefore, an attempt has been made to evaluate the change in water quality on the basis of Strong Acid Cation Exchanger Effluent Conductivity and its impact on demineralised water treatment plant.

Protoplasts (2 x 10(7)/g fresh wt) were isolated from leaves of A. thaliana ecotype estland, with a viability of more than 90%. Protoplasts cultured in calcium alginate beads or layers showed division while culture in liquid or agarose beads failed to elicit any division. Effect of culture density showed highest frequency of division occurring at 5 x 10(5) while no division was seen when cultured at a density of 5 x 10(4). Culture in MS medium resulted in higher division frequency and better sustenance of microcolonies as compared to B5 medium. Under optimized conditions, macrocolonies were formed at a frequency of 1.8%. Shoot regeneration was seen in 50% of microcalli transferred to shoot induction medium for regeneration. Shoots were rooted and plantlets transferred to pots. The plants produced flowers and were fertile.

Molecular investigations during wheat germination have revealed unique developmentally regulated proteins, designated as germins, which show remarkable resistance to broad specificity proteases and to dissociation in SDS. Germins in cereals have an oxalate oxidase activity, which generates H2O2 from the oxidative breakdown of oxalate thereby playing a significant role in plant development and defense. Germin like proteins (GLPs) exhibit sequence and structural similarity with the cereal germins but mostly lack oxalate oxidase activity. Germins and germin like proteins (GLPs) are a class of developmentally regulated glycoproteins characterized by a beta-barrel core structure, a signal peptide, and are associated with the cell wall. GLPs exhibit a broad range of diversity in their occurrence and activity in organisms ranging from myxomycetes, bryophytes, pteridophytes, gymnosperms and angiosperms. Germins and GLPs are thought to play a significant role during zygotic and somatic embryogenesis (wheat and Pinus, respectively), salt stress (barley and Mesembryanthemum crystallinum), pathogen elicitation (wheat and barley), and heavy metal stress, etc. Characterization and cloning of some of the genes encoding germins and GLPs has facilitated a better understanding of their regulation and raised their potential of biotechnological application.

A 10-year-experience with 42 cases of teratomas in paediatric age group is presented. The commonest type of teratoma was sacrococcygeal followed by ovarian and retroperitoneal teratomas. An analysis of clinical profile, malignant potential, management, prognostic factors and follow up is discussed with review of literature.

A retrospective study of 11 cases of choledochal cyst over a period of 10 years is presented. There were 8 females and 3 males in a ratio of 2.67:1. The classical triad of jaundice, mass and abdominal pain was seen in none of our patients. Ultrasonography was diagnostic in 9 out of 11 (80%) patients. Surgical procedures performed were, complete excision of the cyst with Roux en Y hepaticojejunostomy (nine cases), internal drainage of the cyst (one case) and excision of the extrahepatic cyst with Roux en Y hepaticojejunostomy in one case of Type IV choledochal cyst. One patient died in the immediate postoperative period. Others have remained well upto 10 years follow-up. We recommend total cyst excision with hepaticojejunostomy as the treatment of choice.

Total serum LDH and its isoenzymes were estimated in 10 female controls and 30 cases of breast lump (22 malignant, 6 benign and 2 breast abscess). In breast malignancy, there was a significant elevation of total LDH and LDH-3, LDH-4 and LDH-5 isoenzymes with a significant fall in LDH-1 and LDH-2 percentage value. Following therapy, there was a significant elevation in LDH-1 and LDH-2 towards normal with a significant fall in total serum LDH and LDH-4 and LDH-5 isoenzymes. The estimation was found to be helpful in assessing the response of patient to the therapy given.
