Abstract: Protein patterns of eggs, serum and ovarian fluid obtained at 0 to 24h after ovulation in goldfish were analyzed by SD Spolyacrylamide gel electrophoresis. In eggs, no distinct differences in protein patterns were observed although more pronounced bands were noted at the time of ovulation. These prominent protein bands probably representing cleaved products of vitellogenin, e.g. lipovitellin, were indicated by bands at molecular weights 9MW) of 109 and 119 kD, and another class of four small polypeptides (MW=24-32 kD). No distinct bands appeared for phosvitin, the other product of vitellogenin, although there seems to be a substantially reduced band at about 15 kD. Similarly, no differences were observed in the protein patterns of both ovarian fluid and serum. In the ovarian fluid, the distinct bands of 133, 120 and 28 kD were especially prominent at 24h postovulation when eggs were completely overripe. In the serum, the prominent bands appeared at 162, 72, 28 kD; a lower band at 15 kD, which was not observed in the ovarian fluid was noted. These results that there may probably be no further cleavage of proteins during egg overripening in goldfish.

Herbal medicine has provided a steady source of indigenous alternatives to western medicine. Tubers of Stephania sp. Locally known as “biab” in Panay Island, Philippines have long been used by local people to cure a variety of skin diseases and wounds. The study did reveal that the tubers have antimicrobial property which may be due to its alkaloidal content. Crude as well as semi-purified alkaloid crystals consistently showed activities against Gramnegative bacteria (Staphylococcus aureus, Bacillus subtilis) and Gram-positive bacteria (Pseudomonas aeruginosa, Escherichia coli). There maybe more than three types of
alkaloids present in the tuberous roots of Stephania sp., which have been regarded to be the components responsible for its curative power or medicinal value, particularly its antimicrobial property. (with permission from the senior author)

ABSTRACT

Extracts of the microalga Nannochloropsis sp were screened against Vibrio harveyi in vitro. Isolation and purification of bioactive compound responsible for vibriostatic activity were also initiated. Extracts of Nannochloropsis sp. in methanol, n-hexane, ethyl acetate including the aqueous fraction showed antibacterial activities against Vibrio harveyi except the dichloromethane (DCM) fraction. Thin layer chromatography (TLC) analysis showed that extracts may contain cardiac glycosides, phenolics, erpenes, and flavonoids. When bioassayed against V. harveyi, however, only the terpenes and glycosides inhibited the growth in vitro. Terpenes and cardiac glycosides must be present together to effectively promote vibriostatic activity. There was no activity with only the cardiac glycosides present or terpenes in purified form. Several compounds were probably involved and were acting together in an additive or synergistic action on a site associated with vibriostatic activity. Nannochloropsis sp. extracts can thus serve as an alternative treatment to control luminous bacteria disease in penaeid shrimp larvae. Findings in this study may usher in a new era of controlling diseases by using microalga-derived biocompounds.

Abstract:

Calcium has been implicated to be involved in the maturation process. This study examined whether there is a role for calcium signaling in mouse oocyte maturation. Single photoprotein aequorin-injected denuded mouse oocytes were monitored for cytoplasmic free calcium elevations. Complementary data on maturation of denuded mouse oocytes cultured in vitro were also assessed. Denuded mouse oocytes stimulated with 1μM acetylcholine,1μM thapsigargin and 1 mM lanthanum ions enhanced the initial entry into maturation and the final percentage of oocytes maturing compared with the control or progesteroneinduced oocytes with or without the presence of a maturation inhibitory substance, IBMX (isobutylmethylxanthine).
Acetylcholine (1 μM) induced free calcium transients that lasted about 1-2 min.
Lanthanum ions (1mM) gave low pulsatile free calcium oscillations while 1μM thapsigarin elicited a single free calcium transient that lasted about 3 min. Free calcium response was also elicited by acetylcholine stable analogue, carbachol, even in conditions where cyclic AMP level was kept in elevated. Since cytoplasmic free calcium elevations can overcome the inhibitory effects of an elevated cyclic AMP levels and enhanced maturation rates, we propose that calcium must be regarded as an alternative maturation promoting intracellular signal for induction of mouse oocyte maturation.

ABSTRACT

Denuded immature mouse oocytes microinjected with photoprotein aequorin were stimulated with cholinergic agonists, acetylcholine and its stable analogue, carbachol. The calcium transient response of oocytes to both agonists was biphasic and was of short duration. Both antagonists, atropine and pirenzepine blocked cholinergic-induced calcium transients. This indicates that muscarinic acetylcholine receptors are present in the plasma membrane of immature mouse oocytes and are possibly of the pharmacologically defined M1 subtype. In the mouse oocytes, mobilization of intracellular calcium as well as the influx of calcium across the plasma membrane is muscarinic receptor-mediated. The results of the study suggest that muscarinic acetylcholine receptors may have some specific roles in the regulation of mouse oocyte maturation; and that there is indeed a role for calcium signaling in the final oocyte maturation process.
