Effect of SKI 306X, a new herbal anti-arthritic agent, in patients with osteoarthritis of the knee: a double-blind placebo controlled study.

SKI 306X is a purified extract from a mixture of three oriental herbal medicines (Clematis mandshurica, Trichosanthes kirilowii and Prunella vulgaris) that have been widely used for the treatment of inflammatory diseases such as lymphadenitis and arthritis in far East Asia. A double-blind, controlled study was performed to evaluate the efficacy and safety of SKI 306X with placebo in 96 patients with classical osteoarthritis of the knee. Patients were randomized to four treatment groups: placebo, 200 mg, 400 mg and 600 mg of SKI 306X t.i.d.. Clinical efficacy and safety were evaluated for 4 weeks continuous treatment. SKI 306X demonstrated its clinical efficacy, as assessed by 100 mm visual analogue scale (VAS), Lequesne index and patients' and investigators opinion of the therapeutic effect compared with placebo (p<0.01). No significant adverse events were observed in patients treated with SKI 306X. This study demonstrated that SKI 306X, a new herbal anti-arthritic agent provided clinical efficacy in patients with osteoarthritis.

Parental use of the term "Hot Qi" to describe symptoms in their children in Hong Kong: a cross sectional survey "Hot Qi" in children.

BACKGROUND: The Chinese term "Hot Qi" is often used by parents to describe symptoms in their children. The current study was carried out to estimate the prevalence of using the Chinese term "Hot Qi" to describe symptoms in children by their parents and the symptomatology of "Hot Qi". METHOD: A cross sectional survey by face-to-face interview with a semi-structured questionnaire was carried out in a public hospital and a private clinic in Hong Kong. The parental use of the term "Hot Qi", the symptoms of "Hot Qi" and the remedies used for "Hot Qi" were asked. RESULTS: 1060 pairs of children and parents were interviewed. 903 (85.1%) of parents claimed that they had employed the term "Hot Qi" to describe their children's symptoms. Age of children and place of birth of parents were the predictors of parents using the term "Hot Qi". Eye discharge (37.2%), sore throat (33.9%), halitosis (32.8%), constipation (31.0%), and irritable (21.2%) were the top five symptoms of "Hot Qi" in children. The top five remedies for "Hot Qi" were the increased consumption of water (86.8%), fruit (72.5%), soup (70.5%), and the use of herbal beverages "five-flower-tea" (a combination of several flowers such as Chrysanthemum morifolii, Lonicera japonica, Bombax malabaricum, Sophora japonica, and Plumeria rubra) (57.6%) or selfheal fruit spike (Prunella vulgaris) (42.4%). CONCLUSION: "Hot Qi" is often used by Chinese parents to describe symptoms in their children in Hong Kong. Place of birth of parents and age of the children are main factors for parents to apply the term "Hot Qi" to describe symptoms of their children. The common symptoms of "Hot Qi" suggest infections or allergy.

Anti-HIV-1 activity of herbs in Labiatae.

The anti-HIV-1 activity of aromatic herbs in Labiatae was evaluated in vitro. Forty five extract from among 51 samples obtained from 46 herb species showed significant inhibitory effects against HIV-1 induced cytopathogenicity in MT-4 cells. In particular, the aqueous extracts of Melissa officinalis, a family of Mentha x piperita "grapefruit mint," Mentha x piperita var. crispa, Ocimum basilicum cv "cinnamon," Perilla frutescens var. crispa f. viridis, Prunella vulgaris subsp. asiatica and Satureja montana showed potent anti-HIV-1 activity (with an ED of 16 microg/ml). The active components in the extract samples were found to be water-soluble polar substances, not nonpolar compounds such as essential oils. In addition, these aqueous extracts inhibited giant cell formation in co-culture of Molt-4 cells with and without HIV-1 infection and showed inhibitory activity against HIV-1 reverse transcriptase.

Effects of Shikunshito-Kamiho on fecal enzymes and formation of aberrant crypt foci induced by 1,2-dimethylhydrazine.

Shikunshito-Kamiho (SKTK) is a traditional Chinese medicine composed of eight crude drugs (Ginseng Radix, Hoelen, Atractylodis Rhizoma, Glycyrrhizae Radix, Prunellae Spica, Ostreae Testa, Laminaria Thallus, Sargassum). We investigated the effects of SKTK on pH, ammonia, fecal enzymes such as beta-glucuronidase, tryptophanase, urease, and formation aberrant crypt foci in the colon carcinogenesis model induced by 1,2-dimethylhydrazine (DMH). Water extract of SKTK was administered orally for 5 weeks to DMH-treated mice as 0.5% and 1.5% of the diet. Beta-glucuronidase, pH and tryptophanase were significantly inhibited after treatment of 0.5% and 1.5% SKTK, while urease was significantly reduced only during and after treatment of 1.5% SKTK as compared with control data. However, the ammonia concentration wasn't different in SKTK treated groups from control group. The incidence number of aberrant crypts foci (ACF) and aberrant crypts/focus in colon was significantly decreased by 0.5% and 1.5% SKTK mixed diets compared with that in rats treated with DMH alone. These results suggest that SKTK exterts anticarcinogenic activity on experimental murine colorectal cancer.

[Screening test of crude drug extract on anti-HIV activity].

The anti-HIV-1 effects of 204 crude drugs of common use in Japan were evaluated in vitro. As a result, 45 samples inhibited HIV-1-induced cytopathogenicity in MT-4 cells. In particular, the hot water extracts of Lithospermum erythrorhizon (root) and Prunella vulgaris (spike) showed the strongest anti-HIV-1 activities. Their IC100 values were both 16 micrograms/ml. In general, the hot water extracts of the crude drug suppressed the replication of HIV-1 growth more strongly than the cold water extracts.

Molecular systematics of the nepetoideae (family Labiatae): phylogenetic implications from rbcL gene sequences.

Total DNA was extracted from 41 species (20 genera) of the subfamily Nepetoideae (family Labiatae). Using rbcL-specific primers, the rbcL gene wsa amplified by polymerase chain reaction (PCR) and sequenced directly. RbcL sequences were evaluated with character state (maximum parsimony; PAUP) and distance methods (neighbour-joining; MEGA). In agreement with classical systematics all taxa studied cluster within the Nepetoideae and are clearly distinguished from members of the subfamily Lamioideae. A number of distinctive clades are apparent within the Nepetoideae: I-Collinsonia, II-Lavandula, III-Agastache, Glechoma, IV-Satureja, Hyssopus, Dracocephalum, V-Nepeta, VI-Hormium, VII-Prunella, VIII-Melissa, Ocimum, IX-Monarda, Mentha, X-Origanum, Thymus, XI-Salvia, XII-Rosmarinus, and XIII-Perovskia. At least five main branches representing the clades I, II, III to VII, VIII, and IX to XIII respectively, can be distinguished within the Nepetoideae studied. They might be considered representing the tribes (according to Cantino, 1992) Elsholtzieae (I). Lavanduleae (II), and Mentheae (III-XIII). The tribe Mentheae needs to be subdivided into at least three main groups (clades III-VII, VIII and IX-XIII). Majorana hortensis which is often classified as Origanum hortensis does not cluster with Origanum and deserves a genetic status of its own.

Vertebrate host specificity of two avian malaria parasites of the subgenus Novyella: Plasmodium nucleophilum and Plasmodium vaughani.

The susceptibility of wild-caught European passeriform birds to naturally isolated malaria parasites, Plasmodium (Novyella) nucleophilum and Plasmodium (Novyella) vaughani, was studied by means of intramuscular subinoculation of infected citrated blood. Plasmodium nucleophilum of the great tit, Parus major, was transmitted to 3 great tits, but 3 blackcaps (Sylvia atricapilla) were not susceptible. Plasmodium vaughani of the robin, Erithacus rubecula, was transmitted to 1 robin and 1 blackcap, but 1 dunnock, Prunella modularis, was not susceptible. The prepatent period was between 8 and 10 days in all experimental infections. Maximum experimental parasitemia (3.4% of red cells) was detected in great tits infected with P. nucleophilum 23 days postexposure. A light (<0.01%) transient parasitemia of P. vaughani developed in the robin and blackcap. This study is in accord with former experimental observations on host specificity of P. nucleophilum and P. vaughani, which are characterized by a wide, but selective, range of avian hosts. Two new host-parasite associations were recorded.

FASTPAT: a fast and efficient algorithm for string searching in DNA sequences.

A new string searching algorithm is presented aimed at searching for the occurrence of character patterns in longer character texts. The algorithm, specifically designed for nucleic acid sequence data, is essentially derived from the Boyer-Moore method (Comm. ACM, 20, 762-772, 1977). Both pattern and text data are compressed so that the natural 4-letter alphabet of nucleic acid sequences is considerably enlarged. The string search starts from the last character of the pattern and proceeds in large jumps through the text to be searched. The data compression and searching algorithm allows one to avoid searching for patterns not present in the text as well as to inspect, for each pattern, all text characters until the exact match with the text is found. These considerations are supported by empirical evidence and comparisons with other methods.

SIMD parallelization of the WORDUP algorithm for detecting statistically significant patterns in DNA sequences.

The development of new techniques in sequencing nuclei acids has produced a great amount of sequence data and has led to the discovery of new relationships. In this paper, we study a method for parallelizing the algorithm WORDUP, which detects the presence of statistically significant patterns in DNA sequences. WORDUP implements an efficient method to identify the presence of statistically significant oligomers in a non-homologous group of sequences. It is based on a modified version of the Boyer-Moore algorithm, which is one of the fastest algorithms for string matching available in the literature. The aim of the parallel version of WORDUP presented here is to speed up the computational time and allow the analysis of a greater set of longer nucleotide sequences, which is usually impractical with sequential algorithms.

WORDUP: an efficient algorithm for discovering statistically significant patterns in DNA sequences.

We present here a fast and sensitive method designed to isolate short nucleotide sequences which have non-random statistical properties and may thus be biologically active. It is based on a first order Markov analysis and allows us to detect statistically significant sequence motifs from six to ten nucleotides long which are significantly shared (or avoided) in the sequences under investigation. This method has been tested on a set of 521 sequences extracted from the Eukaryotic Promoter Database (2). Our results demonstrate the accuracy and the efficiency of the method in that the sequence motifs which are known to act as eukaryotic promoters, such as the TATA-box and the CAAT-box, were clearly identified. In addition we have found other statistically significant motifs, the biological roles of which are yet to be clarified.

[Comparative study of the spectral characteristics of ursolic acid between laser Raman spectra and IR spectrum].

In this article, HRD2 double-beam grating monochromator was used to record the laser Raman spectra of the ursolic acid and get the Raman spectral characteristics of the ursolic acid; Philips 100 double-beam grating monochronmator was used to record the IR spectra of the ursolic acid and get the IR spectral characteristics of the ursolic acid; the relationship of the wave peaks and the structural characteristics between the Raman spectra and IR spectra was analyzed, the attribution of the functional groups in the structural characteristics of ursolic acid was basically defined, providing two basic spectra areas (area A: 1,386, 1,370, 1,363 cm-1, and area B: 1,304, 1,269, 1,237 cm-1), which identify the matter of ursolic acid; the comparison was made between the Raman spectra and the IR spectra, and showed that Raman spectra are much more informative in structural characteristics than the IR spectra, and the main characteristic peaks of the IR spectra can be found, which correspond to peaks in the Raman spectra; the peaks in the Raman spectra are clear and distinguishable and are used to assign the functional groups easily. In addition to IR spectra, Raman spectra are used as an effective method to analyze natural herbs.
