ABSTRACT: Two parasitic cymothoidae (Crustacea, Isopoda) are reported parasitizing fishes Hemiramphidae in India. Ceratothoa angulata, found in the buccal cavity of its host, is reported for the first time from India. Mothocya plagulophora, a branchial species, already known from the Southwest coast, is now recorded from the Southeast coast of India. Host-parasite relationships are considered.

ABSTRACT: Four cymothoid isopods, parasites of fishes, are reported from India. Two new species, Nerocila poruvae and Joryma hilsae
are described. A full description of Nerocila longispina Miers, 1880 is included and two hosts are identified. The distribution
and hosts of Anilocra dimidiata Bleeker, 1857 are updated. Nerocila poruvae, N. longispina and Anilocra dimidiata were collected
from the Southeastern coasts of India and Joryma hilsae from the Southwestern coasts.

ABSTRACT: The effect of parasitic isopods on the fish Carangids malabaricus was studied. The reduction in gill raker count and gill surface area was observed as a function of infestation. The maximum reduction in respiratory surface area was observed in the first gill arch and the minimum in the third gill arch. Infested fish had extremely pale gills, indicating severe anaemia. Gill rakers were seriously lost, apical edges damaged and out off gill lamellae heavily destroyed. Some secondary gill lamellae were fused or thickened. Between the gill lamellae, callus-like thickening was observed. The histopathological symptoms owing to isopod parasites (Joryma tartoor) were categorised as gross lesions and histopathological anomalies noticed in the present study.

ABSTRACT: The rat kidney H1 oxalate binding protein was isolated and purified. Oxalate binds exclusively with H1B fraction of H1 histone. Oxalate binding activity is inhibited by lysine group modifiers such as 4',4'-diisothiostilbene-2,2-disulfonic acid (DIDS) and pyridoxal phosphate and reduced in presence of ATP and ADP. RNA has no effect on oxalate binding activity of H1B whereas DNA inhibits oxalate binding activity. Equilibrium dialysis method showed that H1B oxalate binding protein has two binding sites for oxalate, one with high affinity, other with low affinity. Histone H1B was modeled in silico using Modeller8v1 software tool since experimental structure is not available. In silico interaction studies predict that histone H1B-oxalate interaction take place through lysine121, lysine139, and leucine68. H1B oxalate binding protein is found to be a promoter of calcium oxalate crystal (CaOx) growth. A 10% increase in the promoting activity is observed in hyperoxaluric rat kidney H1B. Interaction of H1B oxalate binding protein with CaOx crystals favors the formation of intertwined calcium oxalate dehydrate (COD) crystals as studied by light microscopy. Intertwined COD crystals and aggregates of COD crystals were more pronounced in the presence of hyperoxalauric H1B.
