Acta Nutrimenta Sinica 1956;0(02):-
A rapid method for directly determining tryptophan contents in foods and feedstuffs was described. l-5mg dry sample could be completely hydro-lyzed in a teflon tube containing 5N NaOH with 0.5% soluble starch under 145℃ for 4 hours in vacuum (760mmHg). The hydrolysate was then adjusted to neutral with 6N HCL in icebath and diluted by five times with 4M urea solution (pH = 11), and was measured at excitation wavelength 280nm and fluorescence wavelength 368nm. The sensitivity of the method was 5ng /10ml, and the recovery rate of 97-107% were obtained in the range of 1-5 ?g/10ml standard tryptophan. The value of a number of foods and feed-stuffs obtained were in agreement with the literatature values.

Tianjin Medical Journal 2017;45(1):43-46
Objective To investigate the changes and clinical significance of serum procalcitonin (PCT) level in children with acute phase of Kawasaki disease (KD). Methods The serum PCT levels and their changes before and after the treatment in 120 children with KD at acute phase were retrospectively analyzed. According to the results of ultrasonic echocardiography, all children were divided into coronary artery damage (CAL) group and no coronary artery lesion (NCAL) group. According to the presence of gastrointestinal symptoms, patients were divided into two groups (A: yes and B: no ). According to the presence of abnormal liver function, patients were divided into two groups (C:yes and D:no). PCT levels were compared between groups. Results The serum PCT levels were increased at acute phase in 56 (46.67%) patients before the treatment than those in normal children, which were decreased obviously after treatment (P<0.05). There were 31 cases combined with CAL, the rising rate of PCT was 38.71%, which was no significant difference compared with that of NCAL group (49.44%, P>0.05). There was no significant difference in serum PCT value between CAL group and NCAL group (P>0.05). The serum C-reactive protein level was significantly higher in CAL group than that of NCAL group. There were 35 patients combined with gastrointestinal symptoms in 120 KD patients. There was no significant difference in the rising rate of PCT between patients with gastrointestinal symptoms (62.86%) and patients without gastrointestinal symptoms (40.00%, P<0.05). There was no significant difference in serum PCT level between these two groups of patients. There were 42 cases with liver dyfunction in 120 KD patients, the PCT rising rate (52.38%) was no statistically significant difference compared with that of patients with no liver dyfunction (43.59%, P>0.05). And there was no significant difference in serum PCT value between the two groups (P>0.05). Conclusion PCT can reflect the acute phase of KD patients. The increased PCT level may be related with the emergence of gastrointestinal symptoms, even though it cannot predict CAL and the occurrence of liver damage.
