Vietnam Marine medicine Institute was established more than 20 years ago and actively contributed to many fields: examination and treatment for marine workers and people, searching and rescue, remote first-aid consultant, researching and training of marine medicine, consulting for Ministry of Health... In the future, it's the first special and leading institute of Vietnam

Diving medicine is one of the branches of military medicine, and plays an important role in naval development. This review introduces the progress of researches on undersea and hyperbaric physiology and medicine in the past few years in China. The article describes our research achievement in conventional diving and its medical support, researches on saturation diving and its medical support, submarine escape and its medical support, effects of hyperbaric environments and fast buoyancy ascent on immunological and cardiological functions. Diving disorders (including decompression sickness and oxygen toxicity) are also introduced.

OBJECTIVETo study the effect of the submarine training on the antioxidant ability of the submarine men.

METHODS50 sea-training submarine men, 50 land-training submarine men and 50 resting submarine men were randomly selected from some submarine troops. The blood routine, the total antioxidative capacity (T-AOC), the content of malondialdehyde (MDA) and the levels of IFN-gamma in blood plasma, the hemolytic degree of RBC, the proliferation of peripheral-blood lymphocyte (PPL) of them were detected in each group.

RESULTSThe T-AOC of the sea-training submarine men, the land-training submarine men and the resting submarine men significantly increased by turns [(15.38 +/- 3.11), (18.81 +/- 2.45), (20.93 +/- 2.95) U/ml], but MDA and the hemolytic degree of RBC significantly decreased by turns [(2.56 +/- 0.70), (2.12 +/- 0.53),(1.77 +/- 0.56) nmol/ml and 25.72% +/- 1.67%, 21.45% +/- 1.02%, 18.28% +/- 1.37%] (P < 0.05). Compared with the land-training submarine men and the resting submarine men, IFN-gamma [(31.89 +/- 3.52) pg/ml] and the proliferation of PPL of the sea-training submarine men were significantly lower, whereas the red blood count (RBC) and hemoglobin (Hb) were significantly higher (P < 0.05).

CONCLUSIONSubmarine training, especially sea training, may decrease the antioxidant ability.

OBJECTIVETo investigate the effect of nutrition protection on oxidation damage of the submarine men.

METHODS50 submarine men were randomly divided into test group and control group, 25 persons each. The test group member took VitB2 5 mg, VitC 200 mg, GPC capsule 50 mg, once every other day and VitA capsules 25 000 units for every week during the sea-voyage. The total anti-oxidative capacity (T-AOC), superoxide dismutase (SOD), malondialdehyde (MDA), the proliferation of peripheral-blood lymphocyte (PPL), the hemolytic degree of RBC and IFN-gamma were detected.

RESULTSBefore sea voyage, the difference in the T-AOC and SOD and PPL and IFN-gamma and the MDA content and the hemolytic degree of RBC between the test group and the control group were not significant (P>0.05). After sea voyage, the T-AOC and SOD and PPL and IFN-gamma in the test group [(24.08 +/- 0.10) U/ml, (44.85 +/- 0.96) U/ml, (0.29 +/- 0.05) (with H2O2), (0.34 +/- 0.04) (without H2O2) and (34.21 +/- 3.52) pg/ml] were higher than the control group [(21.06 +/- 1.10) U/ml, (42.80 +/- 1.46) nu/ml, (0.23 +/- 0.01) (with H2O2), (0.34 +/- 0.04) (without H2O2) and (31.89 +/- 3.52) pg/ml]. The MDA content and the hemolytic degree of RBC [(2.15 +/- 0.28) nmol/ml and (20.96% +/- 0.10%)] were lower than the control group [(2.44 +/- 0.32) nmol/ml and (23.12% +/- 0.77%)]. The difference was significant (P<0.05).

CONCLUSIONTo add antioxidant nutrients can improve the submarine men's antioxidant capacity.
