Preparing manuscripts with figures and tables for camera repro
duction was a formidable task. Care has been taken for consistency
and typographic accuracy. However, I make no claim that no errors
exist in this volume., I hope, however, that the reader will under
stand and ignore any error and find this compendious volume useful
for numerous biologic studies, physiologic explorations and
clinical app lications of radiolabeled cellular blood elements in
years to come. M. L. Thakur Editor, and the ASI Director
ACKNOWLEDGEMENTS Dr. Max Hardeman of the University of Amsterdam
and Dr. Michael Ezekowitz of Yale University served as the
codirectors of the Advanced Study Institute (ASI). Dr. Hardeman
spent countless hours and contri buted to the scientific program,
took care of mailings in Europe, organized transportation in Italy,
and communicated with the hotel management on numerous occasions. I
cannot thank him enough Dr. Ezekowitz collected some manuscripts
and corrected a few. I am grateful to him. I take this opportunity
once again to thank all the guest fac ulty, who, despite their busy
schedules and time constraints, accepted my invitation and made
valuable contributions to the ASI. I am also grateful to all
participants, who were so friendly and were primary resources for
many lively discussions. They made the ASI profession ally
beneficial and socially enjoyable."
Scintigraphic imaging with radiolabeled blood elements has
continued to be a useful diagnostic modality. The major trust of
recent investigation has been in simplifying labeling techniques
and developing new agents that will label blood elements
selectively in vitro. The VI Symposium of the International Society
of Radiolabeled Blood Elements was held in Barcelona (Spain) during
November 23 to 27, 1992.The conference was sponsored by the NATO
Scientific Affairs Division, the USA Department of Energy and the
Spanish National Health Service. This monograph comprises articles
that represent most of the 85 papers (70 oral and 15 posters)
presented during the symposium. The meeting was attended by 110
investigators hailed from 21 countries. Although lllIn-oxine and
99mTc-HMPAO remain the choice agents for labeling blood components
for routine applications, there was heavy emphasis on developing
new labeling agents that will either simplify the in vitro labeling
procedure, or, even better, will label blood components selectively
in vivo, by injecting the radioactive agents directly into
patients. The degree of success in imaging target lesions in humans
by using these agents has been excellent.
The book provides detailed information on residential status,
relative abundance, conservation status etc. of eight species of
vultures recorded in Kangra valley of Himachal Pradesh. It contains
ecological information on 19 breeding sites of Indian White-backed
Vulture. Information on socio-cultural practices of disposal of
carcasses and accessibility of Diclofenac to the vultures has also
been presented. Most of the breeding sites of Indian White-backed
Vultures in Kangra valley were reported around the roads therefore,
human activity and motor interference was a cause of the concern.
Besides, monkeys were also reported as the source of interference
in some of the nesting colonies.
A total of 322 species of birds belonging to 190 genera, spread
over 60 families and 17 orders were recorded in Himachal Pradesh.
Intensive studies on residential status revealed that of a total of
322 species explored, 289 species showed short or long-range
migrations and rest 33 were residents. Of 289 migrant species, 123
were altitudinal migrants, 72 were seasonal-local migrants, 61 were
winter visitors, 28 were summer visitors, 4 species showed winter
and 1 showed summer influx. Analyses of data on relative abundance
showed that Himachal Pradesh is very rich in avifauna and acts as a
home to 143 very common, 109 common, 47 uncommon and 23 rare
species. Studies on avian diversity along the altitudinal gradient
showed that there was a decrease in bird diversity with an increase
in elevation. An insight into the bird diversity of the localities
separated by altitudinal gradient revealed that the bird species
present in one locality were replaced by another species in other
localities. Based upon present studies it has been found that there
are 11 globally threatened species of birds in Himachal Pradesh.
