Two nematode species of the genus Philometra Costa, 1845 (only females), P. ocularis sp. nov. and P. managatuwo Yamagutl, 1941 were recorded from the ocular cavity and the gonad, respectively, of the serranid fish (grouper) Epinephelus septemfasciatus (Thunberg) from the coast of the Tsushima Island, Nagasaki Prefecture, Japan. The new species is mainly characterized by the presence of four conspicuously large, crescent-shaped, fleshy cephalic papillae of the external circle and two small, subterminal papilla-like projections on the caudal end. Philometra cephalus is transferred to the genus Philometroides Yamaguti, 1935 as P. cephalus (Ramachandran, 1975) comb. nov. The finding of P. managatuwo represents the second record of this species and a new host record.

We examined whether thyroid hormones affect myocardial -PKC signalling, downstream target substrate, connexin-43 (Cx43) and arrhythmogenesis in non-diabetic and diabetic rats. Diabetes was induced by a single streptozotocin injection (50mg/kg, i.v.). Triiodothyronine (T3) was applied by gavage (1µg/kg of body weight for 10 days) to 4 weeks and 9 weeks diabetic and age-matched non-diabetic rats. Western blot analysis of Cx43 and -PKC, immunofluorescence of Cx43, ultrastructure of cardiomyocytes and myocardial conduction velocity were performed. Isolated perfused heart preparation was used to test ventricular fibrillation susceptibility. T3 significantly decreased -PKC expression in non-diabetic and suppressed in diabetic rat heart ventricles. Decline of -PKC signalling was associated with decrease of Cx43 phosphorylation in diabetic and to a greater extent in non-diabetic rat hearts. However, conduction velocity was significantly decreased in diabetic while enhanced due to T3 and increased in non-diabetic T3-treated rat heart ventricles compared to non-treated. T3-induced down-regulation of Cx43 was associated with increased cardiac propensity to ventricular fibrillation. Findings indicate that activation of -PKC signalling linked with phosphorylation of Cx43 is one of the mechanisms involved in the adaptation of the heart to hyperglycemia. Suppression of -PKC and Cx43 phosphorylation by T3 abolish benefit of adaptation rendering the heart prone to lethal arrhythmias.
