ABOUT THE BOOK

Certain areas in all the scientific disciplines have changed dramatically in the past few decades, while other areas in the same discipline have remained static. Evaluative specturm during the past two decades in the field of medical mycology has swelled markedly due to transplant surgery and the use of corticosteroid, antbiotic and immunosuppressive therapy. Fungal infections, very rare, are common mycoses today and several of the fungi that infects human beings are known to infect various animals as well. The advances made in Medical

Mycology in the recent past are encapsulated in the present volume “Advances in Medical Mycology” (AMM) Written in honour of Dr. O.P. Srivastava, former head, division of Medical Mycology, Central Drug Research Institute (CDRI), Lucknow, on his superanuation and as a humble dedication to his significant and unique researches in the field of Medical Mycology (MM).

This festschrift volume of AMM contains 13 outstanding contributions from reputed scientists, spread the world over, which deal with significant achievements made in recent years in the area of mycotic infections. The book covers host defence mechanisms against yeast pathogens, rhinosporidiosis, keratinophilic fungi, mould allergy, keratomycoses, oral mycoses, animal mycoses, aflatoxicosis,histopathologic and immunohistopathologic diagnosis etc.

Hopefully, this volume should be able to brovide the latest advances and viewpoints made in the area of medical mycology to scientists, teachers, students and the members of the medical profession.it will also provide stimulus for further interesting
researches in this discipline.

CULTIVATION OF PARASITES PROCEEDINGSWORKSHOP ON
CULTIVATION OF PARASITES OF BIOMEDICAL IMPORTANCE
Sponsored by Central Drug Research Institute & Indian Society for Parasitology


Parasitic Diseases are among the major public health problems of tropical countries including india. They infect man and also severally invade domestic animals and wild-life. Non-availability of satisfactory drugs and immunoprophylactic measures pose a serious problem in the treatment and Prevention of these diseases. In addition, the resurgence of diseases like malaria, once considered to be eradicated, due to the development of drug resistance by the parasite has made the situation more grave. Development of effective drugs against sensitive and resistant strains and other control measures are therefore, immediately required. For this a clear understanding of parasite physiology, host-parasite relationship, mode of action of drugs, mechanism of drug resistance, pathophysiology and immune response is of upmost importance. The non-availability of model parasites in quantities sufficient for these studies deters the much expected progress in this field. To alleviate the problem of parasite scarcity each laboratory should have persons well trained in the maintenance and cultivation of the parasites of its interest.

With this aim a two weeks’(November 28 - December 10, 1994) workshop on “Cultivation of Parasites of Biomedical Importance” has been organised at C.D.R.I.,Lucknow in collaboration with the Indian Society for Parasitology. Considering the importance of the subject, the Department of Biotechnology, Government of India and U.P. Council of Science & Technology have very kindly agreed to provide financial support to the workshop.The Workshop offers intensive training in the maintenance, transmission in vitro cultivation, cryopreservation etc,of important experimental parasites and their vectors. The training is supported by lectures by eminent parasitologists providing an overview of the existing knowledge in epidemiology, life cycle, physiology, control measures etc, as well as problems and challenges in malaria, filariasis, leishmaniasis, helminthiasis, amoebiasis and giardiasis. it is hoped that this training would enable the scientific task force Available in the country to be well equipped for facing the challenges in combating these diseases.

We are grateful to the contributors for their full cooperation in the workshop and for providing their manuscripts in time.

ABOUT THE BOOKt

The work presented in this book was carried out by author in Mycology and Plant Pathology laboratory, Department of Botany, Lucknow University, Lucknow, under the guidance of Dr. (Mrs.) K. Wadhwani, Reader in Botany, from November 1982 to October 1986.

The book deals with air borne fungal spora of various outdoor and indoor working environment including the crop fields. The study of air borne organisms broadly comes under aerobiology which concerns with transportation of the pollen being relevant in reproductive biology and fungal spores which affect the plants in cropfields as well as human being working in different environments. Other organisms areviruses, bacteria, algae, protozoans invertebrate, moss, fern spores, minute seeds and many plants and animal fragments.

Present comprehensive treatment on aeromycology is mainly restricted to the impact of air borne fungal spores on plants, their occurrence in micro and macro environment in the disease development. While impact on human beings relates with the occurrence of air borne fungal spores in their ear wax or otitis media (otomycosis), their association with both the symptomatic and asymptomatic nails and their allergenic effect.

The book has been divided into three sections. Section I deals with occurrence, distribution and identification of fungal spores entraped in aeroscope and colonies obtained in petridishes. The dispersal of spores in air at different times of a year was statistically analysed through coefficient of variation (cv). On the basis of cv, their consistency in atmosphere is discussed. Section II includes the relative abundance of fungal spores in micro and macro environment and their impact on some crop diseases, such as white rust, downy mildew, leaf sports and blight of nine varieties of Brassica juncea, flower and fruit rotting of Luffa cylindrica by Choanephora cucurbitarum and Pythium indicum and Pod rot of Cajanus cajan by Cladosporium cladosporoides. Section III deals with the impact of these air borne fungal spores on human beings working in different environments. These are Otomycosis (ailment of ear), Onychomycosis (disease of nails) and various allergenic reactions.

The author is indebted to Dr. (Mrs.) K. Wadhwani, Reader in Botany for her valuable guidance and constant encouragement during the course of present investigations.
The author is thankful to Prof. C.P. Sharma , Head of Botany, Lucknow University, for providing laboratory facilities.

Special thanks are due to late Dr. Jafar Zamil, Reader in Tuberculosis, K.G..’s Medical College, Lucknow, for testing the allergenic reactions of these fungi to the sensitive patients.

The author is grateful to Dr. P.K.K. Nair, Deputy Director; National Botanical Research Institute, Lucknow, for providing Aeroscope, Prof. K.G. Mukerji, Botany Department, Delhi University for helping in identification of various spores and Dr. O.P. Srivastava for going through manuscript and critical suggestions.

ENVIRONMENTAL BIO-POLLUTANTS AND HUMAN HEALTH
Edited by

Sunit Gupta

The Impact of bio- pollutants on the environment is man’s basic problem. The causal agents of illness and stress can be of chemical, physical or biological origin and have a sizeable impact on productivity. Biological contamination of environment has received great attention in recent years as a possible cause of illness at home and at work. In the present book endeavours to identify air borne fungal spore of various outdoor and indoor working environment and their effects on humanity.

It attempts to cover diverse aspects of the subject through critically reviewed papers which have been contributed by experts of the relevant fields. The paper entitled’ Chronological development of Aeromycology in India with special reference to work done in Lucknow’ highlights the development of Aeromycology in India from early stages till now.

In the subsequent paper, Dr. Singh has emphasized that biological contaminants in the environment can raise concensus for the indoor air quality and the health of the occupants in addition to the damage they can cause to the bulding structure, decoration and contents.

In another paper, Dr. Prakash Kumar and his colleagues have discussed various allergic substances which cause different diseases in human beings, pollen grains constitutes the major elements. Though most grains are capable of eliciting allergic reactions, the intensity of their reactivity varies.

Dr. Gupta throws light on various microorganisms present in indoor environment and their relationship with the occupants. These microorganisms originate from different materials such as fecal material, soil, pesticidal, chemical, dusts, cereal grains, animal feed and even from air conditioning systems.

According to Dr. Walter bio-deterioration and bio-degradation have an important role to play for the forensic scientists who must understand how the environment alters the evidences. He must be aware of how environment effects can interfere with his ability to identify evidence.

The organic pigments produced by certain microorganisms produce red spots on the stone artwork, according to Dr. Sorlini these microorganisms are difficult to identify because they modify their physical and morphological characters very soon.

The book encompasses a wide range of contents and as such it is expected to be of much interest to a vast spectrum of scholars.

Finally, we shall fail in our duty, if we do not express our gratitude to the distinguished contributors of this volume who have responded to the invitation warmly and spontaneously. The view expressed here are exclusively those of the authors and not of the institutions to which they belong.

CHEMICAL POLLUTION IN ENVIRONMENT

Authors
Dr. K.P. Singh
Dr. A.K. Srivastava

In the past 15 years there has been a tremendous increase in the production synthetic chemicals. About 700-3000 new chemicals are being added every year in the Environment and Causing alarming level of Chemical pollution. Most of the Chemicals & Particulates pollutants present in the Environment are Halogenated Aromatic Hydrocarbons, polyclic

Aromatic Hydrocarbons, n-hexane and its metabolites, Silica, Asbestos, Coal, Kaolin, fly ash, Agate Dust and Metals, and Known to cause most threatening and painful disease “CANCER” in addition to Immunotoxicity and other lungs diseases. Out of 35000 known chemicals 6000 only were tested and 1000 of them were found to be “TUMOROGENIC” in animals. THUS REMAINING 29000 CHEMICALS ARE STILL IN THE ENVIRONMENT TO BE TESTED FOR THEIR CARCINOGENIC RISK.

The present book “CHEMICAL POLLUTION” deals with the significant achievement made in the recent years in the field of ENVIRONMENTAL TOXICANTS. It covers numerous chemicals used in industries, and are toxic to man and animals;cumulative effects of such chemicals on man and Environment, and assessment of their carcinogenic risk potential. This book will be highly useful for Research Scientists, Bio-medical research Scholars, Environmentalists, Teachers and Students. It will also provide a stimulus for the further interesting researchers in the discipline of ENVIRONMENTAL TOXICANTS.
