| 内容記述 | 1) アコヤガイの生理状態を，組織の比重によって推定しようと試みた。 2) 組織比重の測定は硫酸銅法によった。 3) 器官によって組織比重を異にすること，同一器宮であっても個体の生理状態によって，組織比重に変化を生ずる器官があることが認められた。 4) 生理状態によって組織比重が比較的大きく変化すると考えられた器官は，外套膜（膜縁部及び縁膜部），鰓，生殖腺及び中腸線であった。変化の傾向は，一般に生理状態の低下と共に組織比重も低下すると考えられるが，鰓の比重は環境条件により多く支配され，生殖腺の比重はその発達の程度に支配されると考えられた。 5) 比較的変化の少ない器官は，閉殻筋，足及び血液であった。 6) 器官の組織比重を変化させる要因には触れなかったが，その追及が必要であり，更に生理状態と組織比重の関係を明らかにするために季節的変化の観察，環境条件及び他の生理的指標との関係を明確にする必要がある。 |

| 内容記述 | In order to identify the physiological conditions of the pearl oyster, the authors were used the specific gravity of the organs of the pearl oyster. In this paper, it is reported that the specific gravity of gill, mid-gut-gland, marginal zone of mantle and gonad are changed in the various conditions of pearl oyster. For the determination of the specific gravity copper sulphate method was used. The shell of pearl oyster was opened and very small slices, just half the size of rice grain were cut from the gill, marginal zone of mantle, pallial zone of mantle, adductor muscle, gonad, foot and mid-gut-gland. Blood is sucked up by small injector from the heart. And then blood or each slice was inserted below the surface of the solutions with graded specific gravity from 1.022 to 1.095. The specific gravity of the tissue slice was estimated by the point where it became suspended in the middle layer of a solution of which specific gravity is already calculated by the standardized hydrometer. As may be seen from Table 1, which shows the results of this experiment, there was a gradual change of the average specific gravity of the organs in the various conditions. The various physiological conditions are as follows. A; Native pearl oyster which collected under near the Marine Biological Station attached to the National Pearl Research Lab .. B; The pearl oyster is not suited for insertion operation, as the germ cell is filled in its gonad. C; The pearl oyster is suited for operation. D; After spawning, the gonad becomes to narrow to insertion of nucleus. This group of pearl oyster, also, is not suited for operation. E; Enervated pearl oyster. Fig. 1 shows the average changes in the specific gravity of organs during the course of the artificial spawning treatments or enervation. As the method of determination of the specific gravity is so simple and does not take much time in the procedure we expect to carry out an extensive experiment in this direction. |
