[Effects of light intensity on growth, survival, metabolism and related enzyme activities of Sepia pharaonis.].

An experiment with single-factor design was conducted to investigate the effects of light intensity on growth and survival of cuttlefish (Sepia pharaonis). The specific growth rate, survival rate, oxygen consumption rate, ammonia excretion rate, lactic acid content in muscle, respiratory metabolic enzymes (including hexokinase, pyruvate kinase, and lactate dehydrogenase), supero-xide dismutase, and malondialdehyde in liver were measured in five constant light intensity treatments (10, 30, 50, 70, 90 μmol·m·s). The main results were as follows: The specific growth rate and survival rate remained steady initially and then decreased gradually with the increases of light intensity.

[Effects of light intensity and photoperiod on the embryonic development of Sepia pharaonis.].

We investigated the effects of lumination on hatching of fertilized eggs of Sepia pharaonis, to reveal the best light conditions for its embryonic development. A single-factor experiment was carried out to examine the effects of different light intensities (10, 30, 50, 70, 90 μmol·m·s) and different photoperiod L:D (24 h:0 h, 18 h:6 h, 12 h:12 h, 6 h:18 h, 0 h:24 h) on the embryonic development. The results showed that the effects of light intensity on the hatching rate, fractured yolk sac rate, incubation period, mass of newly hatched larvae and mantle length was significant.

[Oxygen consumption rate of Sepia pharaonis embryos.].

This research was conducted to unravel the variation of oxygen consumption rate during different developmental stages and the effects of different ecological factors on embryonic oxygen consumption rate of Sepia pharaonis. The oxygen consumption rates were measured at twelve deve-lopmental stages by the sealed volumetric flasks, and four embryonic developmental periods (oosperm, gastrula, the formation of organization, endoskeleton) were selected under various ecological conditions, such as salinity (21, 24, 27, 30, 33), water temperature (18, 21, 24, 27, 30 ℃) and pH (7.0, 7.

[Effects of starvation and re-feeding on survival rate, growth and digestive enzyme activities of juvenile Sepia pharaonis.].

To investigate the effects of starvation and re-feeding on survival rate, behavior, growth and digestive enzyme activities of juvenile Sepia pharaonis, the manipulative laboratory experiments were conducted with 0-6 days of starvation and 15 days of re-feeding to reveal the mechanism of compensatory growth. The results showed that starvation exerted a significant negative effect on the survival rate, growth, hepatosomatic index and digestive enzyme activities (P<0.05).

Abdominal lymphangiomatosis in a 38-year-old female: case report and literature review.

Lymphangioma is an uncommon benign tumor that develops in the lymphatic system. Abdominal lymphangiomatosis is extremely rare in adult patients, and the clinical symptoms of this condition are complicated and atypical. We report a case of abdominal lymphangiomatosis in a 38-year-old female who presented with intestinal bleeding and protein-losing enteropathy, as well as lesions in the lung and bones.
