Definitions
- the present invention relates to an agent for improving renal function, which comprises a bacterium of the genus Bacillus, in particular, a cell of Bacillus subtilis C-3102 strain or a culture thereof, and has an action of decreasing serum creatine level.
- Kidney disease is a lifelong disease (excluding acute nephritis, etc.), many illnesses progress with a certain frequency, and eventually become end stage renal failure (a condition requiring dialysis therapy) There is. Because the kidneys have considerable reserve, chronic kidney injury is almost asymptomatic until kidney function drops below 20%. When any symptom appears, it is end-stage renal failure, and kidney disease has often progressed to the stage where dialysis is necessary.
- Creathun is a non-protein nitrogen compound produced from creatine in the muscle, and is an excellent indicator of renal function (glomerular filtration rate) that is not affected by external factors such as diet. Serum creatine begins to rise when renal function is below 50% of normal as kidney disease progresses. During this period, dietary therapy that limits protein and salt intake is the mainstream, and pharmacotherapy is used as an adjunct. However, renal dysfunction occurs at 20-30% or lower, and serum creatine levels no longer normalize even after dietary therapy, and renal dialysis is required when 5–10% or lower.
- Patent Document 1 Tokuhei 4 24022
- An object of the present invention is to provide a drug useful for the treatment and prevention of renal diseases.
- the present invention provides a renal function improving agent comprising a bacterial cell or culture of a bacterium belonging to the genus Bacillus as an active ingredient.
- the present invention also provides a serum creatine level-lowering agent comprising a bacterial cell or culture belonging to the genus Bacillus as an active ingredient.
- the bacterium belonging to the genus Bacillus is Bacillus subtilis, more preferably Bacillus subtilis C 3102 (FERM BP-1096).
- FIG. 1 shows the digestion pattern of restriction enzyme Notl or Sfil of Bacillus subtilis C 3102 strain genomic DNA.
- FIG. 2 shows the transition of serum creatine concentration in subjects who took the renal function improving agent of the present invention.
- Bacteria belonging to the genus Bacillus have long been deeply involved in human diet, and there is a lot of information about their functionality. Something has been reported yet!
- the agent for improving renal function and the agent for reducing serum creatine value according to the present invention is effective for a bacterial cell belonging to the genus Bacillus or a culture thereof, preferably a bacterial cell of Bacillus subtilis or a culture thereof. It is characterized by including as an ingredient.
- the bacteriological properties of Bacillus 'subtilis are described in, for example, Virgie's' manual 'ob' Bataterilogi Vol. 11 (1986), and specifically have the following characteristics.
- Bacillus subtilis used in the renal function improving agent and serum creatine level reducing agent of the present invention include, for example, Bacillus subtilis C-3102 strain (Biotechnology Industrial Research Institute deposit number FERM BP-1096, deposit Dated December 25, 1985). Bacillus subtilis C-3102 soy culture is effective as an additive to livestock for improving gut microbiota, increasing body weight, protecting against infection, strengthening eggshell, improving meat quality, and improving stool odor. (Exclusion 4-24022). The health benefits of this strain are known to include intestinal regulation and reduction of intestinal spoilage products. (Journal of Intestinal Bacteria Vol. 18, No. 2, 93-99 (200 4)).
- Bacillus subtilis C 3102 is characterized in that a fragment of about 700 bps is amplified when a PCR reaction is carried out using PCR primers of the following sequence 1 and sequence 2. Other Bacillus ⁇ In subtilis no amplification occurs with this PCR primer.
- the approximately 700 bps fragment amplified using the genome of Bacillus subtilis C-3102 as a template has the characteristic that it has no homology with the amylase sequence. Is clearly identified. No. 1) No. 2)

- Bacillus subtilis is cultured using edible natural substances such as soybean meal, soy boiled beans, red beans boiled beans, cooked rice, barley rice, wheat bran, boiled corn, and other cereals. Add to the food as it is without separating the cells from the culture.
- the renal function improving agent and serum creatine lowering agent of the present invention are incorporated in food and drink as food additives that may be administered in the form of liquids, powders, granules, tablets, etc. You can do it.
- Examples of the food and drink include beverages, confectionery tablets, pastes, breads, processed fish products, and dairy products.
- the present invention relates to a renal function-improving agent having an effect of lowering serum creatine value, which comprises a Bacillus subtilis cell or a culture thereof as an active ingredient.
- Bacillus subtilis which is an active ingredient of the present invention, is effective in a trace amount and in a short period of time, has excellent preservation and acid resistance, and reaches the intestine and proliferates. I can expect.
- Bacillus subtilis C 3102 strain (Deposit number FERM BP-1096, Deposit ⁇ December 25, 1985) is used as an example of bacteria belonging to the genus Bacillus. Using.
- the subjects were 10 healthy men and women (5 women and 5 men) aged 25 to 40 years.
- Table 2 shows the selection criteria. Excluded were those taking or taking specific drugs or foods for specified health use.
