Evaluation of wound healing effects between Salvadora persica ointment and Solcoseryl jelly in animal model.

In this research study very first time a herbal ointment contain 10% Salvadora persica extract was compared with Solcosseryl jelly 10% and blank Vaseline to evaluate wound healing effects using excision wound healing model in animals. Three groups of rats (n-6) were experimentally wounded on the back of their neck. Group I was dressed with Vaseline containing 10% test drug, Group II was treated with thin layer of Solcoseryl jelly 10% as reference drug while Group III was dressed with thin layer of blank Vaseline as control group. The effect of vehicle on rate of wound healing were assessed and in all cases there were progressive decreased in wound area with time but wound dress with Vaseline containing S. persica extract and wound treated with Solcosseryl jelly significantly healed earlier than those treated with Vaseline. It is concluded that S. persica extract significantly enhance the acceleration rate of wound enclosure in rats.

Cell-based regenerative strategies for treatment of diabetic skin wounds, a comparative study between human umbilical cord blood-mononuclear cells and calves' blood haemodialysate.

BACKGROUND: Diabetes-related foot problems are bound to increase. However, medical therapies for wound care are limited; therefore, the need for development of new treatment modalities to improve wound healing in diabetic patients is essential and constitutes an emerging field of investigation. METHODS: Animals were randomly divided into 8 groups (I-VIII) (32 rats/group), all were streptozotocin (STZ)-induced diabetics except groups III and VIII were non-diabetic controls. The study comprised two experiments; the first included 3 groups. Group I injected with mononuclear cells (MNCs) derived from human umbilical cord blood (HUCB), group II a diabetic control group (PBS i.v). The second experiment included 5 groups, groups IV, V, and VI received topical HUCB-haemodialysate (HD), calves' blood HD, and solcoseryl, respectively. Group VII was the diabetic control group (topical saline). Standard circular wounds were created on the back of rats. A sample of each type of HD was analyzed using the high performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS) system. Wound area measurement and photography were carried out every 4 days. Plasma glucose, catalase (CAT), malondialdehyde (MDA), nitric oxide (NO) and platelets count were assessed. Wound samples were excised for hydroxyproline (HP) and histopathological study. RESULTS: Treatment with HUCB MNCs or HUCB-HD resulted in wound contraction, increased CAT, NO, platelets count, body weights, and HP content, and decreased MDA and glucose. CONCLUSION: Systemic administration of HUCB MNCs and topical application of the newly prepared HUCB-HD or calves' blood HD significantly accelerated the rate of diabetic wound healing and would open the possibility of their future use in regenerative medicine.

[The influence of solcoseryl on population and cellular parameters of HeLa and RD cultures].

Changes of population and cellular parameters of HeLa and RD cultures after introducing of solcoseryl in culture medium were studied by methods of scanning cytophotometry and cytomorphometry. Monolayer density, proliferation activity, the number of dead cells in a monolayer, the number of nucleoli in nuclei and distribution of cells in the populations by this parameter, RNA and DNA masses in nuclei and nucleoli, total volumes and surface areas of the nuclei and nucleoli were determined. It has been shown that solcoseryl differently affects the cultures both on population and on cellular levels of their organization. The results of multi-parametric analysis of the influence of solseryl on the cultures allow considering it as a biologically active compound with the features typical for cell and cell population growth regulating factors.

[Antimicrobial activity determination of the preparations used in comprehensive treatment of patients with parodontitis].

Determination of antimicrobic activity of the preparations of Metrogyl denta, Cholisal and Solcoseryl on the complex culture of microorganisms employing the developed procedure was carried out. Degree of the antimicrobic action manifestation of each preparation was revealed.

Comparative multiparametric analysis of HeLa and RD cell culture reactions to solcoseryl.

Reactions of continuous HeLa and RD cell cultures and their nuclear and nucleolar apparatus to addition of solcoseryl into the medium were studied. The monolayer density, proliferation activity, percentage of dead cells, RNA and DNA content in the nuclei and nucleoli, number of nucleoli in the nuclei, cell distribution in the population by the number of nucleoli in the nuclei, volume and complete surface area of the nuclei and nucleoli, and the nucleolar/nuclear ratio were evaluated. The cultures differently reacted to solcoseryl in the medium at the population and cellular levels of their organization. By the results of multiparametric analysis of the reactions of cells and their nuclear and nucleolar apparatus, solcoseryl can be referred to bioactive substances with characteristics of a factor regulating cell population growth.

[The experimental study on culture of human oral keratinocyte and epithelium using autologous serum and fetal bovine serum].

OBJECTIVE: To investigate the possibility of culturing human oral keratinocyte using autologous serum in order to provide theoretical and technical foundation for clinical application of tissue engineering oral mucosa epithelium. METHODS: The human oral keratinocytes were cultured by the medium containing different concentrations of autologous serum (10%, 20%, 30%)and fetal bovine serum (10%), respectively. The growth conditions for the cell and the mucosa epithelium in the groups were observed, the cell growth curves were drawn, and the population doubling time (PDT) was counted. RESULTS: The results showed that the human oral keratinocyte could proliferate well in the medium containing autologous serum or fetal bovine serum. The differences in the 24-hour clone rate and PDT were not significant. Both the area and the thickness of the cultured oral epithelium increased with the increase of the autologous serum concentration, and the difference between autologous serum and fetal bovine serum was significant, especially with the medium containing 20% autologous serum (P < 0.05). The human nature of the cultured epithelium was demonstrated by the immunofluorescent mouse anti-HLA antigen. CONCLUSION: The autologous serum can replace the fetal bovine serum to culture the oral keratinocyte well, and the cultured oral mucosa epithelium can be better differentiated in the autologous serum than in the fetal bovine serum.

[The optimization of the method of culturing neural stem cells in neonatal rat brain].

OBJECTIVE: To establish a better method of isolating and culturing of neural stem cells (NSCs) in neonatal rat brain. METHODS: Tissue of brain was isolated from neonatal rats. Different medium and culture concentration were used to culture NSCs of neonatal rat. The culture concentration used were 1 x 10(4), 1 x 10(5), 1 x 10(6), and 1 x 10(7)/ml respectively. Ingredient of medium was classified into group 1 to 8 respectively according to whether to add 2% B27, epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF) as well as the difference in culture concentration. The cells were induced to differentiate as to be confirmed as NSCs, and then were checked by phase contrast microscopy and identified by immunocytochemistry. RESULTS: The cells isolated and cultured gathered into neurospheres. The cells were capable of proliferating and maintaining long-term survival in vitro. The cells could be differentiated into neurons and glia. It was to the benefit of the survival of NSCs to add 5% fetal bovine serum(FBS) into the medium at the beginning of the culturing. When 10% FBS was added into the medium, the neurospheres differentiated quickly. When concentration 1 x 10(6)/ml was used, the growth rate of the cells was the highest of all the concentrations. Reasonably higher cell concentration promoted the proliferation of NSCs. It was necessary to add 2% B27, EGF, and bFGF into the medium. The cells had the best growth when 2% B27, 20 ng/ml bFGF and 20 ng/ml EGF were added into the culture medium. EGF and bFGF had cooperative effect. CONCLUSION: A better method of isolating and culturing of NSCs in neonatal rat brain is established and the foundation for future research is laid.

[Use of new solcoseryl-containing Diplan-denta C film in the treatment of injuries of the buccal mucosa]. / Primenenie novoi solkoserilsoderzhashchei plenki Diplen-denta C pri lechenii travm slizistoi obolochki rta.

Clinical efficiency of bilayer adhesive dental film Diplan-denta C with solcoseryl in the treatment of postoperative wounds of the buccal mucosa and the effects of this film on the course of wound process were evaluated. The course of wound process in 39 patients with postoperative injuries of the buccal mucosa treated with Diplan-denta XD and Diplan-denta C films and traditional local therapy (0.05% chlorohexidine bigluconate solution and solcoseryl dental adhesive paste) was compared. In the study group Diplan-denta XD film with chlorohexidine was used for local therapy during the first 1-3 days after the injury and Diplan-denta C film with solcoseryl was used in subsequent days until epithelialization; in controls irrigations of the oral cavity with chlorohexidine bigluconate solution (0.05%) were carried out during the first 1-3 days and applications of solcoseryl dental adhesive paste were made during subsequent days until epithelialization. The results indicate that the use of Diplan-denta C film optimized the treatment of the buccal mucosa wounds.

[A pilot study on the culture and differentiation of bone marrow stromal cells from SD rats].

In order to observe the growth, expansion and differentiation of the cultured bone marrow stromal cells (BMSC), we isolated the BMSC from adult SD rats and cultivated them with LIF and bFGF. Then, we cultured and induced the stem cells by using retinoic acid and the culture medium confected in our lab by ourselves. We found that the BMSC could expand and generate clones when they were cultured in vitro. These cells subcultured grew rapidly and differentiated into neuron-like cells and astrocyte-like cells. The results showed that BMSC have the abilities to self renew and differentiate, thus demonstrating the culture method we used is suitable for the culture of BMSC in vitro. The bone marrow stromal cell is not difficult to obtain; it is capable of expanding and differentiating in culture. If the culture condition is appropriate, it can differentiate into neuron and astrocyte. So, it is a kind of perfect seed cells.

[Solcoseryl: new use possibilities]. / Solkoseryl: novi mozhlyvosti zastosuvannia.

Elementary structure of the medication was investigated. It revealed that such micro- and macro elements as Se, Fe, Mn, Cr, Pb, Sr, Br, Cu, Zn, S, Ca, K, Cl are presented in Solcoseryl. The micro- and macro elements are in a complex with bioligands, which determines a part of Solcoseryl's pharmacological activity or in other words an influence on homeostasis of the organism.

The effect of He-Ne laser (632.8 nm) and Solcoseryl in vitro.

He-Ne laser (632.8 nm) and Solcoseryl (SS), a non-protein calf haemodialysate, were used in the enhancement of wound healing. Nonetheless, a study on the use of He-Ne laser with SS has not been done. The purpose of this study is to determine the effect of He-Ne laser biostimulation in combination with SS on Chinese hamster ovary (CHO) and human skin fibroblast (HSF). A dose response for the cloning efficiency (CE) of CHO and HSF cells in 5% fetal bovine serum in minimum essential medium (FBS-MEM) with 6-125 micrograms/ml SS and He-Ne laser using an optimum power density of 1.25 mW/cm2 and cumulative doses (CD) of 60-600 mJ/cm2 given for three consecutive days, were done. The combined effects of He-Ne laser 180 mJ/cm2 with 6 and 12 micrograms/ml SS were determined. Quadruplicate cultures were done. Student t-test was used to determine differences of treatment groups from controls. CHO and HSF CE were increased using 180 mJ/cm2 laser by 13.1% +/- 4.5% (p < 0.0025) and 39.1% +/- 7.9% (p < 0.0005); SS 6 micrograms/ml by 14.4% +/- 8.7% (p = 0.01) and 20.7% +/- 10.9% (p = 0.01); SS 12 micrograms/ml by 17.7% +/- 6.3% (p = 0.001) and 23.9% +/- 5.6% (p < 0.0025); laser + SS 6 micrograms/ml by 15.1% +/- 8.8% (p < 0.01) and 60.9% +/- 9.4% (p < 0.0001); laser + SS 12 micrograms/ml by 23.0% +/- 1.5% (p < 0.0001) and 70.7% +/- 11.4% (p < 0.0001), respectively. Additional significant increases in CE were observed on CHO using laser + SS 12 micrograms/ml by 8.6% +/- 1.3% (p < 0.025) and on HSF using laser + SS 6 micrograms/ml and laser + SS 12 micrograms/ml by 15.6% +/- 6.8% (p < 0.025) and 22.7% +/- 10.6% (p = 0.01), respectively, when compared to the effect of 180 mJ/cm2 laser. Results suggest that further stimulation can be achieved by using He-Ne laser with SS. This could be exploited as a new treatment modality.

The effectiveness of the haemodialysate Solcoseryl for second-intention wound healing in horses and ponies.

Second-intention healing of limb wounds in horses is often problematic. Solcoseryl is a protein-free, standardized dialysate/ultrafiltrate (HD) derived from calf blood, which has been shown to improve healing in both animals and humans. The efficacy of HD in the healing of deep wounds in horses and ponies was investigated. Deep wounds of 20 by 35 mm were created on both metatarsi (skin, subcutis, periosteum) and on both femoral biceps muscles (skin, subcutis, muscle) of five horses and five ponies. The wounds on one side were treated with HD, four times a week during the period that the wounds were bandaged and once daily thereafter. The wounds on the other side were left untreated. In the first 4 weeks of the healing period HD stimulated healing but inhibited healing thereafter. This pattern was significant for all wound groups (P < 0.001). Because of this change in effect, the overall effect on wound healing over the entire period was not significant (P = 0.77). HD stimulated healing initially by provoking a greater initial inflammatory response, faster contraction and faster formation of granulation tissue. Subsequently, HD inhibited healing because it significantly delayed epithelialization and caused protracted inflammation. The effects of HD were most pronounced in the horses. Because this study distinguished between contraction and epithelialization, it could be shown that HD stimulated contraction but inhibited epithelialization. Therefore, HD is useful in horses for the treatment of deep wounds during the initial phase of healing by second intention, i.e. during the first weeks when wound contraction can be expected. Treatment should be ceased when epithelialization becomes predominant.

[New stimulants of corneal reparative regeneration]. / Novye stimuliatory reparativnoi regeneratsii rogovitsy.

The efficacy of corneregel, a drug containing pantothenic acid, a component of coenzyme A, in healing of corneal wounds has been evaluated. The study was carried out on 19 rabbits (38 eyes) with standard corneal defect made with a 5-mm trephine for lamellar transplantation of the cornea, divided into 2 groups: 1) instillations of corneregel (10 eyes) and 0.25% levomycetin solution (10 eyes) and 2) 20% solcoseryl gel (9 eyes) and 0.25% levomycetin (9 eyes). Time course of changes were evaluated by biomicroscopy (fluorescent test), histologically (hematoxylin-eosin staining), and immunohistochemically after 1, 2, 4, 7, 30, and 90 days. Proliferative activity was studied by expression of the proliferating cell nuclear antigen and the migration capacity of cells by expression of alpha-smooth muscle actin. The terms of epithelialization were as follows: corneregel 10 +/- 7 h, 20% solcoseryl gel 108 +/- 10 h, levomycetin 124 +/- 6.93 h. Earlier epithelialization in the corneregel group was apparently due to increased expression of alpha-smooth muscle actin and increase in the cell migration capacity. Hence, corneregel is recommended for practical use as a stimulant of reparative regeneration of the cornea.

[Neuronal differentiation of human small cell lung cancer cell line PC-6 by Solcoseryl].

Solcoseryl is composed of extracts from calf blood, and is a drug known to activate tissue respiration. In the present study, I demonstrated the cell biological effects of Solcoseryl on a human small cell lung cancer cell line, PC-6, by analyzing cell morphology, cell growth, expression of neuronal differentiation markers, and the ras proto-oncogene product(ras p21). Exposure of PC-6 cells to Solcoseryl at the concentration of 200 microliters/ml induced (1) cell morphological changes, including neurodendrite-like projections from the cell surface, and (2) complete inhibition of cell growth, that was shown by the loss of Ki-67 expression. Solcoseryl also induced the expression of neurofilament protein and acetylcholinesterase, both of which are markers of neuronal differentiation. Moreover, it upregulated the expression of the ras proto-oncogene product, ras p21. Taken together, these data suggest that Solcoseryl is composed of component(s) which can induce neuronal differentiation of the human small cell lung cancer cell line, PC-6.

Influence of "Solcoseryl" during culture on the sex-dependent repair of bovine demi-embryos.

The purpose of this experiment was to determine the effect of culture conditions on the development of split embryos after bisection and on the sex ratio of resultant bovine demi-embryos. Embryos that had developed into blastocysts on days 6 1/2 to 7 or on days 7 1/2 to 8 from oocytes matured and fertilized in vitro were bisected in BMOC-3 medium supplemented with 33% calf serum. The medium also contained 0%, 0.1% or 1.0% Solcoseryl, a deproteinized hemodialysate product from calf blood. The demi-embryos were first cultured for 4 hours in the same medium in which they had been bisected and then co-cultured with cumulus cells in TCM199 supplemented with 1% calf serum for an additional 20 hr. The rate of production of good to excellent quality demi-embryos obtained from days 6 1/2 to 7 blastocysts was higher than from those on days 7 1/2 to 8. The rate was also significantly improved when blastocysts were bisected in medium containing 0.1% or 1.0% Solcoseryl, compared to the medium without Solcoseryl. Male embryos seemed to recover more rapidly than female embryos, as assessed by morphological quality at 4 hr, although the quality of female embryos had improved by 24 hr. The percentage of males after culture was higher in the medium without Solcoseryl than in its presence. Thus, addition of Solcoseryl at either 0.1% or 1.0% to BMOC-3 medium seemed to improve the production efficiency of good quality demi-embryos, but did not influence the sex ratio. It appears as if female demi-embryos required more time than male embryos to be repaired after bisection.

Solcoseryl improves learning and memory in rats.

Our previous experiments have shown that Solcoseryl (S), a protein-free extract of calves' blood stimulates locomotor activity and decreases haloperidol catalepsy in rats. In this study the influence of S on acquisition, consolidation, and recall of both, conditioned avoidance responses (CARs) and passive avoidance behaviour was tested. S at the intraperitoneal (i.p.) dose of 1.25 ml/kg significantly improved acquisition and at the dose of 1.0 ml/kg recall of CARs. In the passive avoidance situation the significant effect on acquisition and recall of information was observed after i.p. injection of 1.0 ml/kg of S, and on consolidation after 0.75 ml/kg. These data indicate that S may positively affect the CNS processes responsible for learning and memory.

Solcoseryl stimulates behavioural activity of rats.

The influence of Solcoseryl (S), a protein-free extract of calves' blood given intraperitoneally (i.p.) on the behavioural measures of activity of the central nervous system of male Wistar rats was examined. The drug (1.0 ml/kg i.p.) given 60 min before testing the animals in electromagnetic motimeter significantly enhanced overall and vertical motility of rats. S at the doses of 0.5, 1.0 and 2.0 ml/kg did not significantly influence the activity of rats in "open field". 1.0 ml/kg of S given 15, 45 and 60 min before thiopental (30 mg/kg i.p.) did not change the onset and time of sleep following the latter drug, except for the significant shortening of the time of sleep of animals injected with S 15 min before thiopental. S at the dose of 1.0 ml/kg did not change stereotypies produced by apomorphine (2.0 mg/kg i.p.) and amphetamine (6.5 mg/kg i.p.) but decreased intensity of haloperidol (1.0 mg/kg i.p.) catalepsy.

Cooperative effects in vitro on fibroblast and keratinocyte functions related to wound healing by transforming growth factor-beta and a low molecular weight fraction from hemolyzed blood.

Blood or its constituents, respectively, contain a.o. substances such as TGF-beta (transforming growth factor-beta), PDGF (platelet-derived growth factor) and other factors, which beneficially influence wound healing. Patients with perivascular disturbances and consequently with inadequate supply of the affected tissue cells often suffer from poor healing of dermal wounds. Here, various cellular functions in situations of poor supply and related to wound healing, such as proliferation, colony formation, and migration of fibroblasts, and of monolayer formation by keratinocytes were emulated in vitro by supplementing cultures with reduced amounts of serum. Computer-aided image analysis allowed to quantify the cellular reactions under normal and serum-deprived medium conditions and under the influence of a low molecular weight fraction manufactured by dialysis of hemolyzed calf blood (HD, Solcoseryl) and of TGF-beta. Both preparations are in use for the treatment of poorly healing wounds. While HD preferentially normalized the reduced viability of fibroblasts, the keratinocyte activity was enhanced by TGF-beta. Restoration of fibroblast and keratinocyte functions proved most effective when combining HD with TGF-beta.
