Abstract

During 1993 to 1996, reproductive aspects of Holothuria scabra, one of the commercially important holothurian species in Indonesian waters were studied, which involved populations of Ambon Bay (eastern Indonesian waters), Saugi Island (central Indonesian waters) and Lampung Bay (western Indonesian waters). Those studies were reviewed in this paper, not only to reveal general patterns of reproductive seasons of populations throughout Indonesian waters, but also to provide more knowledge on gonadaltubule-development that has been rarely investigated on Indonesian holothurians. The review showed that the development of gonadal tubules amongst populations of Indonesian H. scabra were similar. Those included that: tubules across a gonad grew for one single reproductive cycle, and each tubule had equal opportunity to release their gametes in the same spawning event. These features conformed to general characteristics of this species throughout the world, and were different from the proposed tubule recruitment model of Smiley (1988). Each observed population showed fluctuation on gonad index, and individuals with fecund and/or post spawning gonads were recorded in most sampling occasions, resulting in fluctuation of gonad index. This attribute gave clue to through-year spawning activity with more intense during one or two periods in a year.

Abstract

Background: Fractured bone healing requires three to nine months, which prolongs the patients’ morbidity. Long bone fracture is considered to be difficult due to the dependence of bodily mobility and freedom. Bone tissue engineering materials includes hydroxyapatite (HAp), titanium, alumina, and polymers. HAp is found to be heavily abundant in cuttlefish. This study is conducted to prove that the cuttlebone has an effect of accelerating the fractured long bone healing process. Methods: This is an experimental study using a total of 32 samples of Rattus norwegicus. The Treatment Group received the cuttlebone extract + 0.9% NaCl while the Control Group received only NaCL 0.9%. Both groups were fractured beforehand. On the 14th day the fractured area was harvested and assigned for histopathology and radiographic exam. Results: The Treatment Group was found to have thicker callus formation and more osteoblasts. Conclusions: The cuttlebone extract application caused thicker callus and higher osteoblast production, proving an accelerated fractured bone healing process.
