Influence of
Zinc in Acidic Medium on Liver Biochemistry of Channa punctatus
(Bloch)
Sharma, R. L. and Srivastava, N.

Biology Laboratory,
Department of Zoology,
University of Rajasthan,
Jaipur-302004 (India)
The present experiment
was conducted to access the effects of an acidic pH alone and in
combination with 20 mg/L and 30 mg/L of Zinc at ph 6 on the
murrel C. punctatus (Bloch). Zinc at an acidic pH elicits
greater behavioural change in C. punctatus than exposure
to an acidic pH alone. An acidic pH, however, appears to be the
causative factor for changes in body weight; liver weight and
HSL, whereas it tends to have no significant effects on liver
proteins. It lowers liver glycogen and increases liver
cholesterol content. On addition of zinc at an acidic pH, no
appreciable change is brought about in total proteins, while a
non-significant decline is noted in glycogen and a significant
decline is noted in cholesterol.

Haematological
values of Sarcoptic mange infected Hanuman Langurs and its
comparison with the normal values

The Hanuman langur (presbytis
entellus) is a widely distributed non-human primate
of the Indian sub-continent and found in variety of ecological
conditions. A number of recent reports have suggested the
usefulness of the Hanuman langur as laboratory model in variety
of biomedical and virological studies. Little information is
available on the haematological values of infected animals.
Comparison of normal values with that of infected aI1imai values
is useful in selecting animals for experimentation. In the
present study, the investigations were carried out from the
blood samples collected from the free ranging Hanuman langurs
infected with Sarcoptic mange. Haematological parameters
like blood-glucose, blood-urea, cholesterol, creatinine,
bilurubin, SGOT, SGPT, Sodium, Potassium, Calcium. RBC, WBC were
estimated. Results, their importance and comparison with normal
values of langurs and humans are discussed.

Fluctuations in
Dissolved Oxygen Content and Transparency of River Ramganga and
its Tributaries due to Domestic Sewage and Industrial Effluents
Gupta, N. and Khan, A. W.
Department of Animal Science,
MJP Rohilkhand University,
Bareilly-243006 (India).
An attempt has
been made in the present work to estimate the dissolved oxygen
(DO) content and transparency during different months in the
river Ramganga and its tributaries viz. Nakatia, Deorania
and Sankha at Bareilly. Two sites, A & B (A-clear, B-polluted)
were chosen at each tributary. Observations made for a period of
12 months recorded a maximum decline in Deorania tributary of
river Ramganga with a fall of 58.4% in DO and -32.53%
intransparency indicating a higher pollution index of this
sampling station.

Report of Survey of Higher
Vertebrates of Rivers Yamuna. and Ganga (from Chambal / Yamuna
Confluence at Pachnada to Varanasi)
Sharma, R. K.,
National Chambal Sanctuary,
Morena - 476001 (M.P.)
Available information about the
occurrence of higher vertebrates in the rivers of Northern India
is long outdated, besides being anecdotal and fragmentery. The
Yamuna river below its confluence with the Chambal and the
section of the Ganga into the Yamuna flows have not been
systematically surveyed for higher vertebrates so far. Surveys
of the above mentioned sections of rivers have a special
significance with regard to the status of the gharial, because
they can reveal information regarding migration of this species
from the National Chambal Sanctuary, which contains its breeding
populations and in which considerable numbers of captive reared
gharials have been released to supplement wild populations. With
the above objectives, these sections of the Yamuna and Ganga
were surveyed in February 1997. The surveys assumed special
importance for assessment of the effects of severe floods that
occurred in the monsoon season of 1996 on the riverine/riparian
ecosystem of the Yamuna and the Ganga.

Contraceptive
Efficacy of Piper Longum (50(Yo EtOH Extract) with Special
Emphasis on Testicular Cell Population Dynamics,
A. K. Purohit,
Reproductive
Physiology Section,
J.N.V. University, Jodhpur.
The administration of Piper
longum fruit (50% EtOH) extract to intact rats group at the
dose of 1.50 mg/kg body weight for 60 days caused arrest of
spermatogenesis. The diameter of seminiferous tubules and Leydig
cell nuclei were reduced. The production of spermatocytes
(primary and secondary) and spermatids were significantly
reduced (P<0.001; 89.67%, 92.72% and 95.97%). The total
number of immature and mature Leydig cells were significantly
decreased (P<0.001; 71.27% and 80.82%), where as
degenerating cells were significantly increased (55.62%).
Decreased testicular cell population reflect contraceptive or
antispermatogenic nature of Piper longum extract and may
be of vital use in fertility control.

Notes on the
Genus Pseudovelia Hoberlandt 1950 With the Description of a New
Species from India (Hemiptera: Veliidae)
Gupta, Y. C. & Khandelwal V. K
Department of Zoology,
B. S. A. College,
Mathura (U.P.) India.
The Pseudovelia Hoberlandt,
1950, is an important genus of family Veliidae, which is hereto
recorded from West Bengal, India. It is the first record of the
genus from India. A new species Pseudovelia (s.str.) baijali
sp.nov. is described. The Veliidae are perhaps the best
known of all aquatic Hemiptera of the world and are extremely
common in India waters. The members of the family Veliidae are
easily differentiated from the related family Gerridae on the
basis of hind leg not surpassing the tip of abdomen and the
presence of median longitudinal groove on vertex. Pseudovelia
Hoberlandt, 1950 belongs to the sub farnily Microveliinae of
the family Veliidae (China & Usinger, 1949). The genus
Pseudovelia Hoberlandt, 1950 is easily recognized from the
members of other genera due to long, stout and curved antennae
which extended more than 2/3 length beyond apex of head, blade
like ventral arolium and cone shaped small proctiger which is
caudally directed in female.

Total Body
Lipids and its Iodine Number in Relation with the Reproductive
Activity of
Rhinopoma microphyllum kinneari
Purohit, A. K. and Gaur, B. S.
Department of Zoology,
JNV University,
Jodhpur-342005 (India)
Total body lipid
(g/100 g dry body weight), its Iodine number and gross body
water composition (g/100 g fresh body weight) were recorded from
an insectivorous desert bat Rhinopoma microphyllum kinneari
during reproductively active and inactive conditions which
suggest that body lipid and its Iodine number decrease during
active phases. The body water composition in female is elevated
during their active phase while the male shows the reverse of
it.
