1.Extraction of carpamic acid from leaves of carica papaya L, Caricaceae
Pharmaceutical Journal 1999;282(10):12-13
Carpamic acid was an alkaloid as a hydrolysate from carpamic alkaloid in the past. Today, the carpamic acid is extracted from leaves of carisa papaya L. by many ways and isolated by column chromatography so it is proven as originated from leaves of carica papaya L. caricaceae.

3.Investigation on biological effects of some species from the branch Crinum, Amaryllidaceae, on experimental model Artemia salina
Pharmaceutical Journal 1999;282(10):23-25
Screening of water, MeOH, ether extracts from all parts of some Crinum species has been conducted using the Brine shrimp microwell cytotoxicity assay. The water, MeOH extracts from the root, bulbs of all studied Crinum species and the water, MeOH extracts from the leaves of C. latifolium analyzed showed toxicity to the brine shrimp (LC50<1000 m/ml). the most promising extracts (LC50 < 300 m/ml) were the total alcaloid extracts from all parts of Crinum species.

4.Investigation on the inhibitory effect of the mitosis from the extract of some species of Crinum on the bulb of Allium ascalonicum L
Pharmaceutical Journal 1999;282(10):17-20
The methanolic and water extracts of leaves, bulbs and roots from 5 species (C.sp1, C. sp2) were subjected to Allium antimititic test, of those methanolic extracts showed strong activity, especially the leaves extracts of C. latifolium, C.sp1, C.sp2. Total alkaloid of all samples exhibited a strongest activity. Furthermore, the water, methalonic extract and total alkaloids had clearly an inhibitory activity on the elongation of Allium roots.

5.Study on alkaloids extracted from leaves of C. latifolium L. Amaryllidaceae by technical GC-MS.
Pharmaceutical Journal 2000;291(7):9-11
A rapid and sensitive capillary column gas chromatographic mass spectra (GC-MS) method for determination of cranium latifolium derivative alkaloids is reported. Well resolved, sharp and symmetrical peaks were obtained for compounds of these alkaloids. The 15m DB-5 and 30m DB-5 capillary columns were used for this purpose, and the time of analysis of all derivative compounds was 25 min. This procedure required only small amounts of dried plant material.

Background: Psychological factors such as anxiety and depression have been recognized as the etiology of temporomandibular disorders. Objectives: The study aimed to evaluate the prevalence of temporomandibular disorders in dental students and describe the state of depression and anxiety and related factors in the students with the disorders. Materials and methods: 323 students at the Faculty of Odonto-Stomatology, Hue University of Medicine and Pharmacy, were examined to detect temporomandibular disorders, using the DC/TMD axis I. Then GAD-7 and PHQ-9 questionnaires were used to screen for anxiety and depression in the group with the disorders. Results: The proportion of students with temporomandibular disorders was 38.1%, intra-articular disorders accounted for the highest rate (80.5%). The percentages of depression and anxiety among students with the disorder were 28.4% and 55.3%, respectively. 41.5% of TMD students had mild anxiety and the same proportion of students had risk of depression. Risk factors associated with depression and anxiety were economic status and excercise, respectively (p < 0.05). Conclusions: The percentage of students with temporomandibular disorders is relatively high. The majority of students with the disorders are at risk for depression and low level of anxiety. There is a link between the economic status and depression, between exercise and anxiety.
