Status of water pollution in relation to industrialization in Rajasthan.

India is a large and densely populated country; its economy is largely agricultural. Making the best use of the country's manpower has always posed a challenge. Industrialization could become a dominant component of the economy and displace agriculture. Traditional livelihoods of occupational groups are threatened by the practice of disposing untreated industrial waste into rivers and bodies of water. These uncontrolled disposals impact local natural resources with negative long-term effects. Industrialization is the development of intellectual and financial trade that changes a predominantly rustic culture into a modern one. Many industrial units discharge wastewater locally without treatment. Many industries directly discharged their waste into lakes, rivers and ocean. Water contamination impacts the environment. Pesticides, chemical, waste oil and heavy metals are regularly transported into their waters. Humans and other living organisms can accumulate heavy metals from industrial discharges in their tissues. Industrial waste may be reactive, corrosive, flammable, or toxic. When untreated sewage is emptied into rivers, it causes diseases like typhoid, dysentery and cholera. Natural elements and plant supplements like nitrate and phosphates stimulate growth of algae on the water surface. The algae reduce the oxygen in the water and cause eutrophication. It is harmful to the water ecosystem. In Rajasthan proper, there are a number of sites bordering rivers and lakes where the pace of industrialization has proceeded far beyond the ability of regulators to establish and enforce meaningful limits on the amount of point source pollution permitted to the various industrial complexes, which include cement, chemical, fertilizer, textile, mining, quarrying, dyeing and printing facilities. The scale of the problem is obvious to the casual observer, but actual documentation of the total impact remains to be done.

Broad spectrum antidermatophytic drug for the control of tinea infection in human beings.

During antifungal evaluation of various plant extracts, free and bound flavonoids of Piper betle were found to be most effective as an antidermatophytic against human pathogenic dermatophytes Trichophyton rubrum, Trichophyton mentagrophytes, Microsporum gypseum and Candida albicans. Dermatophytic fungi cause both superficial and internal mycoses. These mycoses, although normally not lethal, are unpleasant and difficult to cure and cause considerable financial losses. Earlier workers prove that allopathic drugs are still found effective against dermatomycoses, but these drugs could not be accepted as a routine treatment for every case, because they are expensive and require long treatment. It is almost unaffordable by middle and lower class people. In view of such prospects and constraints, our aim was to explore more new compounds of plant origin for controlling dermatophytic infections. Author explored water, methanolic and flavonoid extracts for screening as antidermatophytic agent. Plant extracts that showed good results in vitro were selected for clinical studies. The study may give cheaper treatment for medium and lower class patients suffering with tinea and may provide them much relief. Well-established paper disc method was used for the screening of different extracts of their antidermatophytic activity. Moreover, it did not exhibit any adverse side effect on mammalian skin. Flavonoids in the form of ointment Pi be I and Pi be II were subjected to topical testing on patients attending out patients department of S.M.S. Hospital, Jaipur, India. Patients were diagnosed as tinea corporis, tinea capitis, tinea manum or tinea pedis. All patients showed positive potassium hydroxide (KOH) results at the beginning of trial. Patients between the ages of 3 months to 58 years were enrolled. At the end of treatment, while 64% of patients cured completely, 24% showed significant improvement and 12% showed little improvement from the disease. Allopathic treatment took 4-8 weeks when compared with only 1-5 weeks taken by Pi be I and Pi be II ointments. The ointment, thus not only showed maximum affectivity but was also found to be a better and cost effective alternative to allopathic drug for tinea infections. The acceptability of alternative medicines, particularly herbal medicines, has now become a critical need of the times.
