This paper deals with the study on the sexual and vegetative reproduction of Sargassum fusiforme. The authors also propose a inference that Sargassum fusiforme relies mainly on the vegetative reproduction of rhizoid while making sexual reproduction subsidiary to maintain the population propagation.

Objective To investigate the clinical and radiologic features of posterior reversible encephalopathy syndrome (PRES) associated with preeclampsia-eclampsia.Methods Twenty-one cases of PRES associated with preeclampsia-eclampsia were retrospectively studied on some aspects of clinical and radiologic features.Results The most common clinical presentations were seizures( 18 cases ),headache (16 cases),altered mentation (15 cases) and vision change (12 cases). Vasogenic edema lesions distributed in the parietal or occipital lobe (20 cases),the frontal lobes (14 cases),temporal lobes ( 11 cases), and basal ganglia (11 cases). The splenium involvement occurred in 4 cases,cerebellar hemispheres and brain stem involvement was prcscnted in 3 cases and 1 case separately. Three major patterns of PRES included dominant parietal-occipital (7 cases),the holohemispheric watershed (7 cases),and superior frontal sulcal (6 cases).Partial and asymmetric expression of PRES only occurred in 1 case.Conclusions The clinical features of PRES associated with preeclampsia-eclampsia are typical.Except the parietal or occipital lobe,involvement of the frontal lobe,temporal lobe and basal ganglia is common,followed by the occasional presence of the splenium,cerebellar hemispheres and brain stem.Three primary PRES patterns are noted,occasional with partial and asymmetric expression of PRES. Awareness of these typical and variable characteristics is important to recognize the PRES ncurotoxicity morc accurately when PRES present.

Pulmonary ventilation function of 22 patients with idiopathic scoliosis was assessed. The results showed that there were significantly lower in Vital Capacity, Vita! Capacity % in predicted, Inspiratory Capacity, Forced Vital Capacity, Forced Expiratory Volume in Is, Maximal Voluntary Ventilation, and Maximal Voluntary Ventilation % in predicted of patients than those of age and sex matched normal controls. And there was no any statistical difference of Tidal Volume, Forced Expiratory Volume in Is % in predicted, Maximal Middle Flow, and Maximal Middle Flow % in predicted between two groups. Furthermore, the reduction of Vital Capacity % in patients with idiopathic scoliosis was correlated with the Cobb Angle, Wedge Index and rotation degree of the top vertebral body and not with the scoliosis direction and the patients' age.

27 rabbits were divided into normal group(n = 4),control group (n = 5), silybin group (n = 6), hyperbaric oxygen (HBO) group (n = 6), and HBO combined with silybin group (n = 6). Circulation of hindlimb was interrupted completely for 6 h and reperfused for 1 h. Malondialdehyde (MDA) and superoxide dismutase(SOD) in plasma from ischemic-reperfused injured limb were measured. Adenosine triphosphate (ATP) and creatine phosphate (CP) in samples taken from anterior tibial muscle were determined. Ultrastructural changes of injured muscle were observed. The results showed that HBO combined with silybin treatment had a favourable effect on ischemic and reperfused injured limb muscle with reduction of the lipid peroxidated injury, increase of the SOD activity and the high energy phosphate compounds (ATP and CP), and a promoting recovery of injured muscle cells. HBO and silybin had a synergistic action. It suggests that HBO combined with silybin is an effective method for treatment of ischemic and reperfused injured limb.
